Bolt Action Pen for Uni PowerTank Refills
Description
A bolt action pen that fits Uni PowerTank SNP-10 refills. I couldn't find a body that would fit standard Uni PowerTank SNP-10 refills so I tried to design my own. I have included a version of the body that is split into a Tip and Barrel, with threads attaching the two parts together. Be very careful with the threads as the walls around that area are quite thin. (I am a 3d design noob so if you have any suggestions for improving the threads, please let me know.) I suggest printing with layer heights < 0.16mm with tree and scarf seams on. If you are printing the threaded Tip, I suggest printing with the tip down. Minor sanding or scaling may be required to get everything to fit well depending on your filament and printer. Keep in mind that the bolt and the clip path will break in with a little bit of use and become smoother.
