Anyone have success using sten mags printed in PLA+ ? It seems the magazine(15rd lower) cant firmly hold multiple rounds without rounds just popping off the magazine. Im guessing 100% printed magazines arent ideal. Maybe I should try STEN mags but with the RR metal inserts.

Thoughts ?

The creep tendency of PLA+ often leads to problems with magazines. Sten are particularly problematic since spacing of the feed lips when new leaves no margin. The only long term reliable Sten mags I've printed were PPA-CF and PET-CF. I suspect Siraya's new PET-GF would also work well.
