Kar98k bolt action pen remake (replaceble cartridge, easy print, designed support, easy writing, durable)

This is a remix from printable. Although I ended up remaking every single part.
**Too hard to keep description on both sites up to date. So check out the printable page for details & instructions: **https://www.printables.com/model/1268374-kar98k-bolt-action-pen-remake-replaceble-cartridge

Kar98k looking pen. Tried my best to keep the visual design while making it functional & durable.

Update:

5/11: Added split file. For slicers that can't split stl to different objects

5/12: Instruction video. As promised

12/21: Come back to make some as christmas gifts. Damn, so meticulously designed. Did I really make this? Added some QOL changes: Beefed up the supports so it's easier to print in matte/silk PLA. Rounded the stock plate connector. A square hole on top of such a tall and thin print fails too easily. Added two small holes on the bullet, so pliers can hold on to it while it's being painted. The furniture is supposed to be printed in different color, and is now in a separate file. Also Im releasing step. Anyway marry christmas!

###features:
Printablity:
Designed to be easier to print
Added design supports. Shouldn't need generated support/brim
Latch on connecting parts. Stay together much better. No need for glue

Writing:
Front sight moved back. This way you can see the tip when writing. So it's an actually somewhat practical pen
Muzzle is screwed on. Cartridge can be replaced without full disassembling

Design:
Remaked the mechanism from the ground up. When the breach is opened the bolt can spin freely. (Took me so long to get this right)
bullet shaped cartridge plug!
