About this model

Tested and working with the Well R2. Solid enough to be used as a grip but hold on the adapter itself not the mag. The all in one file has the orientation i use when printing, i use automatic supports. My settings are 0.3 layer height, 15% gyroid infill and 3 perimeters using basic PLA. The catch uses a M3 19mm screw, a nut and a pen spring around 9 mm long. It is design to be a snug fit, it requires a good clean up of the support remains after printing and inserting it a bunch of times for smooth operation. After cleaning, in case of the adapter not catching in the magwell you may need to scratch with a knife o sand the flat part of the upper tooth (the longer one) just a little bit. Based on this remix of the original:
