Modular air cannon shells

This is my Modular shell system for air cannon rounds. I have two reasons for releasing this, First one cost, when you print air cannon rounds it can get expensive fast so this way you only have to print the core shell once or twice then you can just print the modular attachments. Reason 2, when I was testing my air raid shell I noticed that the housing around the turbine broke almost every time it hit something so with this you only have to reprint the top of the shell.

I have also stopped remixing a premade air cannon shell and have come out with my own design which is what I used for the base of this. I will be uploading the regular non modular shell.

Along with the core shell I have uploaded a normal nose cone, the modular rail and a test slider so that you can check if the tolerances work on your specific printer. I also shared the rail with you so that you can design your own modular attachments.

If you do design you own shell make sure to leave at least 0.5mm of clearance
