Bolt Action Pen - Takes Parker g2 Cartridge

thingiverse

This is my take on the Simple Bolt Action Pen, and I'm thrilled with how it's turning out. It's a fantastic design and a great creation, but I didn't want to have to pull the ends off Parker Jotter (G2) cartridges to get them to fit. I lengthened the pen by about 10 millimeters overall and redesigned the pen stopper, which was no easy task. I admit my design isn't as refined as others, but it's the best I could do with what I've learned so far. I only started learning this stuff a few hours ago. The stopper will print with an offset hole on its side that fits an M3 screw. The shortest end of the stopper, from the hole to the end, is the one pointing toward the tip. I'd love to open up this design to accept Pilot G2 refills, which are about the same standard size as roller ball pen refills, but for now, that's outside my current skill level.
