Bolt-Action Pen with Side Clip

thingiverse

I liked the original design, but I wanted it to have a little pocket clip on the side like most pens, so I used Tinkercad to add one on there. The top cap was also changed to have a bevel, and the parts were split up into separate files for easier handling. EDIT: I added a version with an improved clip and a more ergonomic grip design, which is labelled 'MKII' in the file. I ran out of black PLA, so I printed it in 3DWarhorse Blue PLA and spray painted it gloss black to give it a sleek finish. Note: I've confirmed that this also works perfectly with Pentel EnerGel 0.5mm Needle Tip ballpoint refills from Amazon.
