This is a modular holster adapter for a battle belt. it supports safariland QLS. This is my 4th prototype. I had a demo of this printed in PLA and it snapped under normal operating conditions. I have since changed the design and printed in PET-CF. I have about 50 hours in it not without issues. It includes the brackets for a leg strap and to go around a belt. You will need basic holster hardware to screw these together.
