So I printed it 100% scale and it works well and looks nice, but when I held the sword under a light, looking at it from below, I could see that roughly a quarter of each blade segment was inside it's prior blade segment. Does anyone know if there's another model or a scale I can change it to, to get this sword to be longer?
Only a quarter inch? I normally aim for 1-1.5", don't you want it shorter? Anyways, if you want it longer make sure you don't have any elephants foot on the inside of the segments. If so, remove it with a exacto knife. Otherwise to change length you can try adjusting your flow rate/extrusion multiplier.
Hab den Griff in zwei teile Gedruckt und die Klinge in einer anderen Farbe zu drucken. hab natürlich gleich mal die spitze abgebrochen ;-). also dann halt auch noch die Klinge in Einzelteile gedruckt und den griff wieder geöffnet :-). Aber ich liebe es halt
p.s: gedruckt mit ender 3 und gefunden über @marsgizmo (danke dafür ;-) )
i cant get the blades to print out properly and I'm getting different results between the cura and Orca, i prefer to print on Orca but i can't get good prints with 0.9 line width... cura makes smoother blades but they shoot through each other, orca makes very rough blades.. so idk
Alright so, my printer is weirdly makes bridges every layer and it makes the blades stick. How can I fix this? I own the adventurer 3 pro by Flashforge and I think it might just be the printer itself and the fact that its equipped with a giant 0.4 mm nozzle and has small printing dimensions so when I reduce the size, it fails. Great quality file though and its definitely not your fault. Thanks.
I think it'd be tricky on a resin printer as each segment of the blade (and the handle) are unvented volumes / cups, so it's likely they'd deform. You could cut a hole to vent this and make it work. Cleaning would also be difficult. And postcure as well, since you'd have to postcure in its extended state.
So I tried again without changing the size and after having lost of trouble with this new printer with problems with the prints sticking to the bed and leveling issues and I thought I had fixed it and it worked for a few hours and I come back to it moved and filament everywhere. I am probably not going to do big prints for a while and I don’t understand what Ike doing wrong and I honestly regret getting this printer at this point. It’s an Ender 3 btw
The first layer of mine is stuck together and I’m not sure what I should do lol. I sized it down because I wasn’t sure about the size but I realize now that is wasn’t the best decision. Any advice?
You could also try the removable blade version, its more setup but easier to tune the blades because they can be printed in vase mode. Also maybe slightly stronger too.
If the first layer is fused, is a result of your nozzle being too close to the bed. This causes the line width to be thicker, its called "elephants foot" which can result in the print fusing. Adjust your first layer height so its higher.
In regards to scaling, it is not a good idea to scale smaller unless you reduce your nozzle size. This is because the walls are two nozzle width thick. If you make it smaller the printer has to try to extrude smaller than the nozzle which is difficult.
Brake it apart to tell what is causing it not to extend all the way, then update print setting to get it to function correctly. At least that's what I do. Extending and retracting them a lot seems to help too.
Printed pretty well on my Ender 3 S1 with 7 year old Makerbot black sparkle PLA. I did concentric printing for this one. It doesn't fully extend, but I will try to use silicon lube and work each piece out. I'm missing about 200mm of length based on world's "825mm in total length" statement. Pretty happy with it, even if I can't get it fully extended.
Make sure its not elephants foot from the first layer keeping it from extending. You could measure the thickness of the blades and compare that to what its set at in the slicer. (Make sure there is no elephants foot) This would tell you if its overextending. If its not, it must be from the layer seam size which could be helped with retraction setting.
Hope that helps but honestly with a 7 year old, get the replaceable blade version because they will break. 🤣
Hi would like to sell this product to make some extra money I will probably sell it on Etsy or some other online shop and ship them to the customers. I am still In school so some extra money would be great and I really like your designs if I can't sell this specific model is there any other models / designs I can sell. I am quite young so having some money growing up would be helpful so if you could get back to me that would be great all I need to know is if there are any fees.
Thank you 😊
My test print was able to come apart but should the 3 peices be able to lock into one another like the full size version? Or is the test strictly to make sure your layers don't weld together?
Its hard to give this information out because each printer is different. Its thin wall so its most important to have your layer seam dialed in. See the test print.
I have a MakerBot Sketch that the Buildplate is too small for, it says that I have to scale it down 50% and to fit on the build plate, would this work?
Has anyone tried this yet on a Bambu X-1 Carbon printer yet? Would love to know what material, settings, supports, etc...you had to use to get it printed great. Thank you.
I have been trying to print this, but it seems the segments are completely fixed along one edge of the inside of the blades. I don't think this is a First Layer Adjustment but I'm still new-ish at these adjustments - anything you can recommend I look at?
That sounds like a layer seam issue. Find the test print linked above and adjust your retraction setting; distance, speed, coat, wipe, extra retraction distance, ext.... to achieve the best seam.
Printed pretty clean. However, the blades don't come all the way out, only about a third each. As if they were too thick at the base. i broke of the base and they look clean I think I'll sand them down and see if that helps, but I would love to know if anyone has any ideas as to how I messed it up? printed with .4mm nozzle and .2 layer height in pla+
If the issue is not your bottom layer being too low causing elephant foot, bad layer seam, bad surface finish, then your printer is probably extruding wider than it thinks it is. To get this width correct you need to "calibrate your extruder". You can google this if you want but in short, if you reduce your "extruder multiplier" by .05mm or so, it should fix this issue.
Yes, there is a link in the description above. If this is your first time on a printer you may consider trying a smaller print and place test print first.
If it is of use to anyone, I had struggles with layer shifys on my Ender 3 S1. Besides printing very slowly (I print at 10mm/s) and assuming nothing mechanical is out of whack, enabling acceleration control in Cura and bringing that way down (100ms2) finally solved it for me
I am going nuts trying to figure out the issue I have - printing blades separately using vase mode. Each blade prints perfectly, up to about 2/3 the way up then I start getting what looks like layer shifting on the x axis (Ender 3 S1, eSun Silk PLA). It is less obvious on the bigger pieces, looks terrible on the smaller blade. I've done all the troubleshooting I can think of - levelling the bed, levelling the bed, levelling the bed, adjust belt tension, adjust printing parameters, change the nozzle, adjust Vref, rotate the parts, different slicers, adjust z offet, work on bed adhesion... No luck
If it is of use to anyone, I had the same struggles on my Ender 3 S1. Besides printing very slowly (I print at 10mm/s) and assuming nothing mechanical is out of whack, enabling acceleration control in Cura and bringing that way down (100ms2) finally solved it for me

Awesome, 0.44 line width and 5mm wipe = perfect. Even with acceleration set to max. I did need to set my z-probe a little lower, but thats maintenance.
How can I solve the the sword not expanding all the way on just the tip? The rest of the sections
seem fine but the tip only expands about 1/3 of the way. Test print is fine and wall width is ~0.85mm. When I am printing this, I can tell the center part has less space between the next section than the other sections.
Prusa MK3S+ with PrusaSlicer 2.4.1
Extrusion is set to 1 because no issue with test or other sections.
EDIT: Printing the blades separately from the "removable blade" model, extends all the way. I suspect this is something with the way PrusaSlicer slices.
I’ve printed this twice and neither sword comes out. After taking it apart it looks like the layers are getting fused together at the top of the print (bottom of the sword). How do I fix this?
I tried printing this, but I had to scale it down to fit on my printer, and whenever I tested it out, the blade would not come out. Any ideas on how to fix this?
If you scale it down, only do it in the Z, unless you change your nozzle. Scaling down in the X and Y will make it hard for your printer to print a smaller line width than the nozzle.
I had the same issue (also using a resin printer, so I suspect that the blades fused together some while curing). I plan on trying this model so I can print all the blade pieces separately:
https://www.thingiverse.com/thing:4715295
i printed this a little bit smaller (id say to around 140mm) to fit my printer but it isnt working, i just took it out, do i need to wait a bit? the nozzle size is the same
Justintmoher could be correct. If you scale it down without reducing the nozzle size it could cause issues. I would either only scale Z, or change to a smaller nozzle.
Hello,
I am a student at university. I want to earn pocket money from selling 3D models, and, I want to produce and sell some of your designs. would you let me sell your designs?
If you have a fee for your designs, I am waiting for your response.
Have a nice day...
I don't license my collapsible sword designs for a few reasons. Most notable, I believe having free STL's helps encourage people to get into 3D printing instead of just purchasing a print from someone, which grows the community.
I just made it, but it doesnt actually come out. Not sure what I should do in my slicer. (for context I used basic settings on Cura with the Ender 3 V2)
I haven't printed this model yet, but I'm getting ready to print a similar one. Did you try setting your Z seam to "random"? That way you won't have a potentially solid ridge of plastic up inside the print.
Sorry but it doesn't scale well because its designed to be two walls thick with a .4mm nozzle. If you scale it down and keep the .4mm nozzle the slicer will have to try to make two thin walls or a single wall which is a harder print.
made it works great and of course i broke it first time using it. fixed it with super glue good as new. FYI don't slam it on the ground to put it away like a baton.
Discussions — Collapsing Katana
On my first print all the blades shot out. Funny but was hoping the blades would stay when extending
I would guess your printer is under extruding. Turn up your flow rate/extrusion multiplier or better yet, calibrate your extruder.
you can lightly use a heat gun on the ends of the extending bits but I mean VERY lightly
I've tired this before, its tricky but it works.
mine is not coming out and the blades are stiking together how do i fix this?
I ensured good z offset and level on lower speed. It worked
Find the test print and work on reducing the size of the layer seam with retraction settings.
So I printed it 100% scale and it works well and looks nice, but when I held the sword under a light, looking at it from below, I could see that roughly a quarter of each blade segment was inside it's prior blade segment.

If so, remove it with a exacto knife. Otherwise to change length you can try adjusting your flow rate/extrusion multiplier.
layer 22 is showing as a solid piece in my slicer everything else prints perfectly but because of this all the blades stick together.
First time I've hear of this, what slicer are you using?
Works great but don't shrink it down.
True! Unless you use a smaller nozzle.
Hab den Griff in zwei teile Gedruckt und die Klinge in einer anderen Farbe zu drucken. hab natürlich gleich mal die spitze abgebrochen ;-). also dann halt auch noch die Klinge in Einzelteile gedruckt und den griff wieder geöffnet :-). Aber ich liebe es halt

Glad you like it! 😊
Wonderful design! 🙂
salve ho scaricato il progetto ma mi dice che impieghera 1 giorno 2 ore e 48 minuti io non ho ingrandito ho rimpicciolito il progetto è normale?
Oh, Its a hard first print. I think the nozzle is a little low on the first layer. Is it only fused there or the other layers too?
flow rate or z ofset problem
This turned out awesome, after the 4th try! First two was bed adhesion, 3rd was because my cat attacked my printer (not normal) Overall 4.5 Stars
can i please print this model and sell it, me and a couple of friends want to start a 3d printing business and think this would be a great product
I have a commercial membership.
is it supposed to print with all the pieces inside of itself
yes, they should come out after its printed.
Hi what settings do i use Im using a anycubic kobra plus.
i cant get the blades to print out properly and I'm getting different results between the cura and Orca, i prefer to print on Orca but i can't get good prints with 0.9 line width... cura makes smoother blades but they shoot through each other, orca makes very rough blades.. so idk
Make sure you are changing the line width in the correct place, you have to change it a few places.
what print speed do you print on?
what infill do i use?
20%, its not important.
Alright so, my printer is weirdly makes bridges every layer and it makes the blades stick. How can I fix this? I own the adventurer 3 pro by Flashforge and I think it might just be the printer itself and the fact that its equipped with a giant 0.4 mm nozzle and has small printing dimensions so when I reduce the size, it fails. Great quality file though and its definitely not your fault. Thanks.
I'm having a hard time understanding what is happening. Can you post a picture on our FB group?
so i have a 2mm nozzle should i make the file 50% smaller?
You don't have it, it would be easier at 100%. I'm assuming you meant .2mm.
I tried twice with a .3 mm nozzle. Both times the blade would not come out. Scales were 75% and 90%.
mine doesnt come out
what app did you design this on
The blades come out perfectly, but the get stuck when I am trying to push them back into the handle. Any tips?
I hold it by the blade and slam the pommel on a table.
Any suggestions for settings on an Anycubic Kobra 2 printer? The blades don't extend as far as they should. Thanks in advance.
What is the wall thickness
set it at .45mm
Can this be printer on a ender 3 ?
yes, it printed fairly well on mine
how about simply an ender?
there's no such thing
is the sword 40 grams and if not what can I scale it too
can i get mine now no rush
Yes! Try the test print first
Would this work on a resin printer
I think it'd be tricky on a resin printer as each segment of the blade (and the handle) are unvented volumes / cups, so it's likely they'd deform. You could cut a hole to vent this and make it work. Cleaning would also be difficult. And postcure as well, since you'd have to postcure in its extended state.
IDK, everyone asked but no one confirms... I might be getting one and I may try the dagger first because its smaller.
Would this work on a resin printer
I've never tired but have also never seen anyone show a successful print.
Could you upload a wakizashi to go along with this?
That would be cool! I'm working on a updated version. As soon as I figure out the wrap I want, its giving me a hard time, I'll make a wakizashi too.
So I tried again without changing the size and after having lost of trouble with this new printer with problems with the prints sticking to the bed and leveling issues and I thought I had fixed it and it worked for a few hours and I come back to it moved and filament everywhere. I am probably not going to do big prints for a while and I don’t understand what Ike doing wrong and I honestly regret getting this printer at this point. It’s an Ender 3 btw
This is not a easy print, maybe try some other prints and get more familar with your new printer and give it another go in the future.
The first layer of mine is stuck together and I’m not sure what I should do lol. I sized it down because I wasn’t sure about the size but I realize now that is wasn’t the best decision. Any advice?

how do i make it come out more than the first peice
Brake it apart to tell what is causing it not to extend all the way, then update print setting to get it to function correctly. At least that's what I do. Extending and retracting them a lot seems to help too.
if i had just a little mini problem with the print on the part that sits on the bed should i do some settings ?
First layer problems? You need a really good adhesion for the center blade because there is not much contact with the bed and its pretty tall.
Printed pretty well on my Ender 3 S1 with 7 year old Makerbot black sparkle PLA. I did concentric printing for this one. It doesn't fully extend, but I will try to use silicon lube and work each piece out. I'm missing about 200mm of length based on world's "825mm in total length" statement.

look at support. Under there a link for Patreon says that if you subscribe to the most expensive you get to
bro use commas
My test print was able to come apart but should the 3 peices be able to lock into one another like the full size version? Or is the test strictly to make sure your layers don't weld together?
Its to verify the segments don't stick together. If its really clean you should be good.
do I use scafolding or not?
Supports? No.
what are the common print setting for this?
Its hard to give this information out because each printer is different. Its thin wall so its most important to have your layer seam dialed in. See the test print.
hice una prueba chiquito y no funciono depues baje la altura de 181 a 150 pero con los mismos parametros de x y Y y salio muy bien
I have a MakerBot Sketch that the Buildplate is too small for, it says that I have to scale it down 50% and to fit on the build plate, would this work?
Nope, I would not try to scale this model down.
Has anyone tried this yet on a Bambu X-1 Carbon printer yet? Would love to know what material, settings, supports, etc...you had to use to get it printed great. Thank you.
Yes, I've seen at least a few! I don't have one so I don't know the settings but no supports.
Can I scale this down to 50% and it still work?
Probably not, its going to be tough to get it to work that small.
im very new to 3d printing and when i printed this the blade fuses together and i have no idea what those settings are... can someone help?
I made some detailed instructions if that helps but you will need to know some general print settings as well.

is there any virus
tf, why woulf there be, it is from a popular person
no
why no layers on the bottom for the blade part the handle has a first layer but the blade part does not ??? is that normal ?
Do you need to toggle on/off layers?
I SHALL FORCE MY DAD TO PRINT IT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
why the **** do you need to pay $100+ for A print
Someone is charging Benjamin's for these? 🤣
Hi is there a not printed in place version? im new to 3d printing and im using an anycube kobra and this is my first print and its sticking together.

HOW DO YOU DESIGN SUCH A MASTERPIECE!!!!!!!!!!!!!!
Lots of practice! 🤣
How can I solve the the sword not expanding all the way on just the tip? The rest of the sections seem fine but the tip only expands about 1/3 of the way. Test print is fine and wall width is ~0.85mm. When I am printing this, I can tell the center part has less space between the next section than the other sections.
Prusa MK3S+ with PrusaSlicer 2.4.1 Extrusion is set to 1 because no issue with test or other sections.
EDIT: Printing the blades separately from the "removable blade" model, extends all the way. I suspect this is something with the way PrusaSlicer slices.
Was the center blade getting loose from the bed half way up and causing it to wobble. Just a guess....
please just tell me if you need supports...
No supports needed.
i tried to put it on my 3D printing software but the file was to big
I specify the height of the model in the description. You should be able to set that as your max height in your slicer. Make sure scale is uniform.
I’ve printed this twice and neither sword comes out. After taking it apart it looks like the layers are getting fused together at the top of the print (bottom of the sword). How do I fix this?
Sounds like your bridging is the issue. If your fan is already at 100%, I would try to turn down your bridging speed.
for Ender 3 pro can i print right off the bat or do i need to scale, im new to 3d printing
Height is under 200mm so it should print unscaled. If you have your slicer configured correctly, it will alert you if it is outside of the print area.
I tried printing this, but I had to scale it down to fit on my printer, and whenever I tested it out, the blade would not come out. Any ideas on how to fix this?
the software that I use automatically sales down x and y when I scale down only z
If you scale it down, only do it in the Z, unless you change your nozzle. Scaling down in the X and Y will make it hard for your printer to print a smaller line width than the nozzle.
I had the same issue (also using a resin printer, so I suspect that the blades fused together some while curing). I plan on trying this model so I can print all the blade pieces separately: https://www.thingiverse.com/thing:4715295
cool
can you make a print file like jole showed in community uploads
Could you pass the correct cure setting for printing? Please
I'm no help, I don't use cura. Maybe someone else can help out. You might want to also specify what printer you are using
i printed this a little bit smaller (id say to around 140mm) to fit my printer but it isnt working, i just took it out, do i need to wait a bit? the nozzle size is the same
Justintmoher could be correct. If you scale it down without reducing the nozzle size it could cause issues. I would either only scale Z, or change to a smaller nozzle.
My guess is that shrinking it reduced the space between each blade and caused them to stick together
why will this print take 1 day and 7 hours?
12 hours in my ender 3
I want to say in the 14 hr range on my Prusa.
Would it be ok if I where to sell this on Etsy? Is there a fee? Could I use your photos?
I have a tier in my patreon for those who want to sell my models. Please do not use my photos. If you have any questions feel free to message me.

looks cool
do i need to add supports or are none needed?

I don't license my collapsible sword designs for a few reasons. Most notable, I believe having free STL's helps encourage people to get into 3D printing instead of just purchasing a print from someone, which grows the community.
What layer height do you recommend print this at?
I print at .2mm but you could go higher.
i havent tried it yet but try 0.3mm res and 20% infill
After waiting 35 hours, the sword does not come out, what to do???
Wow, that is a really long time to print this. Did your test prints look ok?
I just made it, but it doesnt actually come out. Not sure what I should do in my slicer. (for context I used basic settings on Cura with the Ender 3 V2)
I haven't printed this model yet, but I'm getting ready to print a similar one. Did you try setting your Z seam to "random"? That way you won't have a potentially solid ridge of plastic up inside the print.
Sorry but it doesn't scale well because its designed to be two walls thick with a .4mm nozzle. If you scale it down and keep the .4mm nozzle the slicer will have to try to make two thin walls or a single wall which is a harder print.
Does this scale well as I am looking to print it but at normal size it will take over a day to print. I want to shrink it down to 75%
If you scale down, you probably have to use a smaller nozzle, in your case 0.3mm. Print the test before a few time until it's perfect.
its great
made it works great and of course i broke it first time using it. fixed it with super glue good as new. FYI don't slam it on the ground to put it away like a baton.
