Bolt Action Pen

thingiverse

Inspired by the innovative designs of bolt-action pens made by Mussy and Begal. While their creations are impressive, I found several aspects lacking due to personal preferences. I sought a design that would not require additional hardware beyond the pen insert and spring, offering effortless adjustability for various pen sizes. The bolt mechanism incorporates a built-in lever with the endcap sealing off the slide channel of the body, securely capturing the bolt in place. The body's width accommodates diverse lengths, making it easy to fit most pen inserts available. Potential future enhancements include: Revising the endcap to be screw-on or twist-lock instead of relying on an interference fit. Adding texture to the grip area of the pen for enhanced user experience.
