modified Gingerneer gustav shell

These are the top 2 sections of the shell for Gingerneer's Carl Gustav. https://cults3d.com/en/3d-model/game/airsoft-carl-gustav-m2-40mm-shell-launcher-minimal-hardware-parts-vfc-compat-gingerneer
This should allow you to use the cylinders for his Gardena Nipple Gas Release system he has on his 60mm mortar. https://cults3d.com/en/3d-model/game/60mm-airsoft-mortar-bicycle-pump-air-pressure-minimal-hardware

Unfortunately as I am completely out of filament as well as away from my printer for a week so cant prove it but all the hack and slash work on the computer was using his original stl files.
There had to a few compromises to squish everything in so the shell is a little longer and the barrel section is a little shorter but still with enough rifling to give a bit of spin.
