I've made this pencil case for my wife, she wanted a case for her pencils so I've made this one as a test for fittings so later i can go for a bigger 48 pencil one, but that's future me problem...
I printed it in PETG and it works well on that. 3 or 4 walls and 10 to 20% infill should do, there's a small part that may need support on the Side B, but other than that just print them on their back and everything should be fine

there are 2 versions for this box, with or without magnets, i've just printed one (with magnets) and glue the 6x2mm disk neodimium magnets on the holes with super glue, but you could use the no magnets version, i'm just not sure if the fittings will be good enough for retain the Top part closed with the Side B of the case. The magnet one is snappy and should be good to use, but maybe a little ugly and with exposed magnets because of small clearances for it on the Sides/Top walls...

assembly:
this is pretty simple, print the parts and cut some spare filament on the holes as pins for the connections , i used black PETG for the pins and heat the ends to form heads on either end, that works pretty fine and had no issues with it

if You want to remix it or give any suggestions, just go ahead!
the project is made on Onshape: [here](https://cad.onshape.com/documents/f2ba85a9c5ffef7ef72d4f60/w/22ad773ed0c075827f24b371/e/4924eef7edb5d6303c9896e1?renderMode=0&uiState=669ec94eea7aa56251cf5c73)

Durable 12 Pencil case

This is the base for my DIY enclosure, made with 3d printed Fittings and 490mmx25mm (outside diameter) PVC pipes. I've made 8 fittings in PETG  (one for each corner) and then wrap a transparent PVC sheet (we use it as table cover)  around, cut and glued with universal glue. 
I added velcro at the ends of the bottom, so they wrap around the pipes, and join the the other part in the inside for ease of removal/installation.
and i also used velcro to help close the "door" (I've made it just with the same material, without gluing the front with the sides)
it works well, I've printed a lot of things in abs and PETG in it with no problems at all, and even without additional heating, just if the bed heat
it can be used at a Creallity ender 3 v3 KE (the one i have) without the spool holder at the top, but i guess most of the ender series should fit too, and if any thing just cut the PVC pipes in bigger sizes.
I'm also planning adding a aluminum sheet on the top of the box (under the plastic) to serve as a table for some tools for the printer, but nothing too heavy

i made this mini boxing Ring for my dummie 13, its a little small in the XY (220x220mm) but they're not really fighting soo... i build that size so i can print all parts in my Ender 3 V3 KE without cuts our gluing, but I think with small changes it can be made more at scale

i've printed ir with PETG and ABS, but i guess any material should do,  ABS you may have issues (as i did) with the dimensions because of shrinkage, but with some material configuration that should be fixable

The one corner pad on the photo ended up unfinished because of print problem i had at a 80% print, but the part still ended up working well,  I'm also going to reprint them in different colors later so no worries...

the model is pretty simple to print and assemble, you will need: 
**Parts:**
- 1 floor
- 1 base
- 4 corners
- 4 poles
- 4 ropes

**Assembly:**
- Align the base and the floor and put 3 poles at the holes.
- Add the 4 ropes pieces on the slots and the rise a little the poles and squeeze the forth one in place with the ropes already directed into the slot, then put them in place again (if some problems with the dimensions of the floor holes or the rope being too big  to put on the pole in the spot, you may want to try printing with xy hole compensation the floor and base or with xy size compensation for the ropes)
- just finish fitting the corner pads on each corner 

- or you could also just assemble all the ropes, poles and corner pieces first and then fit all poles in the roles at the same time

hope you enjoy my creation, any suggestion just leave a message and remixes can be done no problem (I'm even thinking about making the floor part with some roles for the [DUMMY 13 - Acrobatics pedestal](https://www.printables.com/model/692455))
i if you want to modify the model, here is the link for the Onshape project [here](https://cad.onshape.com/documents/bbd9b6bb99251861dca48aee/w/f773fb3a4f7ad6927411c432/e/024a2d8108c757d134a633db) have fun!
