Mag Pull Bumper for Jet Blaster Katana Mag/Clip

thingiverse

9/29/18 Update: New, better design. I made these looser so a square of duct tape on each corner of the mag secures instead of pure friction fit. I wanted to print mag bumpers after a friend lost one of his magazines for several hours at war. Why mark it with a sharpie or tape when I can print something custom? At first, I tried Jet Blaster's bumpers but they were a little chunky and loose fitting. I decided to design my own. I used the Katana STEP from Captain Slug's Caliburn katana magwell file for the design. I made these pretty thin-walled so they fit in HeathWanderLust's mag carrier (https://www.thingiverse.com/thing:2728234). This is a very tight friction fit, I suggest printing at 101 to 102% if not more. If your print is too large, place a strip of duct tape on the bottom corners of your katana mag. This will provide enough friction to secure the bumper (I did that to secure Jet Blaster's bumper). Print on the flat part of the pull tab (approx +/- 65 degrees of rotation).
