Amazing tolerances right off the bed. Printed with Sun lu PLA+

I've printed out loads of these, Picatinny and M-Lok, for my airsoft bb launcher. I printed out of PLA+, PETG, TPU for AMS and I love them all. The TPU version is the best because this TPU is still very rigid and tough, but has enough flexure under the stress of the hardware to flex and form to the handguard. I've used these for many all-day-long events with no failures. I strongly recommend @KP Design's projects. This creator has a lot more great options for other airsoft accessories too.

Printed out of Bambu's TPU for AMS and it is a perfect foot roller or even good for rolling out smaller muscle groups like upper traps, shins, palms, and forearms.
