CZ Scorpion Micro S2 Barrel Nut Removal Tool

Test printed and used successfully at .3mm w/ 100% infill using PLA. Print time about 1 hour.

Wasn't sure how much torque would be needed or how the plastic "teeth" would behave so I went for a more balanced "load application" with the double handle design. Might have been overkill but it worked all the same. shrug emoji

It's a perfectly snug fit. Some tolerance issues may arise depending on printer settings. If need be a light tap with a rubber mallet or similar should persuade her into place.

Did you find this via google but don't have a 3D printer? Are you near a Lowes? These supposedly work, too: https://www.lowes.com/pd/3-Piece-7-5-in-Stainless-Steel-Adjustable-Wrench-Set/1000374705
