Sten Gun Magazine Loader

thingiverse

The other Sten Loader seemed very weak, so I broke four of them (made with 100% infill, PETG) in two weeks. Figuring a better design was needed, I created this heavy-duty loader. The walls are 4mm thick and the pusher is chamfered all around for extra support as well as being longer. To get the best results, use PETG or ABS but PLA will likely work too due to the design's heavy-duty nature. Printing with 'Raft' enabled can help prevent peeling issues when there are radii involved. Print it as-is to avoid wasting plastic on unnecessary supports. This loader is designed for Sten magazines, but it should fit any 23x39mm magazine meant for 9mm ammo. I updated the design to shorten the thumb and chamfer, allowing more room to slide in the bullet.
