Sharpie S-Gel Tip Replacement

I recently got some Sharpie S-Gel pens and the grip was too wide. I could cut the rubber grip off and it worked but where's the fun in that. I created this using OpenSCAD. The intent is to print without supports, not have an obvious seam, and be usable off the printer. The last point is a small stretch, I do recommend post processing with a drill bit for the nozzle hole and for the ink well, just to cut down on rough spots so the pen movement is smooth. This is a straight up replacement for the existing tip. It requires the original spring. Remove the old tip, put the spring into the print, insert ink, screw it onto the rest of the pen. It will sorta cut threads. It's tight but works. Enjoy! Original post: https://www.thingiverse.com/thing:7120473
