After watching Hand Tool Rescue and Chris Borge's video on an antique fractal vise, I also can't resist making one of my own. My aim is to design one that is fully 3D printable without using any fasteners or metal lead screws and at the same time to be printed without any supports. It's not going to be as robust as Chris or Teaching Tech's design simply because plastic is not going to be as strong as metal. So why do it? Because I don't have those parts and I'm lazy to source for them. Just kidding ok. I just want to challenge myself to what extend 3D printing can achieve and also to brush up on my CAD skills. I'm not an engineer so I made an unnecessarily complicated design but it is fun and I definitely learned new things along the process.

I use Fusion 360 to design the model. While trying to maintain a supportless design I tried many different options but I still end up with the dovetail design. I do not want to use any external fasteners so this limits the design options further. In order to print the dovetail without support, I split them into 2 parts. The lead screws are another weak point so I made them to be printed horizontally on the bed instead of vertically.
I also took the idea of the folding handle from Teaching Tech's design.

The smallest clamps are a pain to work with. You may need to scale them bigger by 3-4% if you find them too tight to fit, although all the clamps have 0.3mm clearance between them. Do a test print for fit testing. I do not have an idea how to fully retain the smallest clamp in place so feel free to suggest or remix them.

Printing the parts:
-All parts should be printed as per uploaded orientation without any supports.
-Refer to the name of the STL for how many units to print for each part.
-All parts were printed with 20% infill except for the Mainbed at only 10%. Not necessarily need to follow this.
-The Clamp holder A/B was printed with adaptive layer heights in prusaslicer for a smoother surface on the curve part. (higher resolution on the curve area, lower resolution on the not so curve area)
-Watch out for elephant foot when printing the lead screws
-The C-clamp is included but I do not suggest using them unless you are able to print it in very strong material.
-Some glues are recommended for the handle and large clamp clip if they are too loose.

Fully 3D Printed Fractal Vise (Small)

ClampHolderA.stl

A small size blower made for the purpose of inflating an inflatable bed. Didn't want to bring along a big and heavy blower for my camping trips. This one uses a small dc motor powered by a 5v USB. The one shown in my video is using 10k rpm but it works much better with a 20k rpm motor or higher. The impeller was designed to fit on an 11 teeth gear. I use plastic gear because the motor shaft will be too hot for PLA to withstand. How firm the bed can be inflated depends very much on the power of the dc motor but for this application, it's just enough for my little kids' weight.

Non printed parts required:
DC Motor for reference: https://s.click.aliexpress.com/e/_9GPcvq
Plastic Gears: https://s.click.aliexpress.com/e/_9RpH1i
2 x M4 8mm screw/nuts

The adapter is optional but should be printed in TPU. This is what connects the blower to the inlet of the inflatable bed.

Mini Blower

Impeller.stl

2 part print without support.  This also allows different color print for the base and top.
Print the base and screw into the speaker.
Print the top and press fit (0.2mm tolerance) into the base.  Assuming the 30mm screws can be screwed into the speaker holes of at least 15mm.

Update 19/03/2021:
Added version 2 of the rollers with bigger gears.  The 1st version gear tooth tends to wear out after a packet of seeds.  All other components remain the same and does not need to be reprinted.

This is a sunflower seed peeler. The groove cater for various size of sunflower seeds. Hopefully it's big enough. All parts print without support. I recommend to print more perimeters (4-5) and higher infill for the 2 rollers.

Gently push the sunflower seed down into the appropriate groove while rotating the knob.

Enjoy the seeds!

I love all kind of nuts, pistachio being one of them. But it's always a pain to split the shells. There are a couple of design but they are either not strong enough or the travel isn't long enough to split them open effectively. So i design this.

Do you still have those free measuring tapes from IKEA? Ever wonder how to keep them organised? Here is a 3D printed case that helps to spool and dispense them......quickly.

Just roll them on the flat surface and see the tape disappear into the spooler.

You'll need to print the Grip with TPU. Alternatively, a proper size rubber band should work well too. I use TPU because it looks nicer on it.

IKEA FREE MEASUREMENT TAPE SPOOLER & DISPENSER

Shell.stl

Another toothbrush holder but i wanted something that is enclosed and easy to take in/out. Can be printed in place without support or printed separately with some supports on the hinges.

Assembly is easy, just insert some filament into the 3 hinges.
Start with the 2 hinges at the side, then break them loose before inserting the middle hinge. Else, just break loose all the hinge and insert the filament subsequently.

You can redesign the top cover to anything else.  Unfortunately i'm not sure how to share the diagram for the measurements in thangs.  It doesn't allow uploads of images.  You can get the required measurements at the link below instead.

Enclosed Toothbrush Holder

If you want to print this (print in place version), print it with the bottom on the bed. Not the back on the bed as shown here.  Make sure to turn on bridging.  Refer to the video for the printing orientation.

Toothbrush Holder v4.stl

This is a remix from WalRit easy print design for a Pen/Stationery/Tool holder. Total height is about 140mm.

Cura tree support recommended for the backpack section.

Suggest to print with Tree support using Cura for the backpack.
