Spacer to take the wobble out of the rear trunnion. Nice tight lockup with any sized backstrap fitted. Tested with Gen 3 & 4 no problems.

Two models for G17 & G19, only differences is the width. Print on flat side, no supports necessary. Adjust Z axis in slicer if the fit isn't quite right.

High infill % as they can deform with use (but basically disposable so no problem), or just print sold (100%). PETG or ABS will work best.
