printable ar-15 trigger test jig

A printable ar15 test jig, the structure should be strong enough to hold the spring force, havn't test it out because I'm not an American. So, you American folks are welcomed to give it a try . Posting some photos would be even better.Notice i also give space for the auto sear system.Print it with 100% infill, pla+ would be preferable. If you want to install the grip, use a 1/4 28tpi tap on the bottom hole. You may also need some drill work.
