M40A6 Foam Dart Sniper Shell

You can print this shell for the shell ejecting M40A6 Dart Sniper Rifle. 

My version of the shell is a little bit slimmer than the original one. Using the original meassurements always lead to the shell getting stuck when pulling back the bolt, so i adjusted it. This should work perfectly fine now. If you close the bolt while holding the trigger (not priming the spring) the ejection will be less forceful but still happening.

Depending on your printer and settings you might want to smooth down the shell a bit. Especially if using multiple printed shells in the mag you will hear noises when they are rough

This shell could also serve as a base for engravings or other adjustments :)
