Manticore Magazine Nerf Drum Springs

Uses nerf drum springs instead of spring. Before you hook the top of the drum you need to push the bottom tab back into the inside of the feed lips part, will secure the spring. Also would highly recommend you attach the springs to the follower before gluing the whole magazine. I just used a 5mm allen key through the middle of each spring and carefully moved them into their slot after i dropped the follower in. Sometimes the spring gets misaligned or tangled, just slightly undo them and coil them back up. If it could of supported just 2 i made a tool for it but 3 is a bit too hard for my brain to do. 

Bit of a pain to put under the follower but will sit in there and not move horizontally, just rolls vertically well.

No idea if it actually cycles as my manticore isn't operational, will update when new recoil spring comes.
Also uses m3 heat insert for the base plate, its hella deep so can fit most inserts.

M3 machine screw to hold base plate in place, i used m3 x 10 but i think it can accommodate up to 15mm.

For printing when doing the cover plate for the bottom i would recommend doing supports just the corner where the opening is, and have it bridge most of the horizontal bit. Clean up with knife and should friction fit pretty good. Inserts and screw to ensure it is secure.

Will provide cad file, but I'm pretty trash at cad so it isn't the best.

Big thanks to shirley productions, he is a sick cunt for posting his work for free.
