Print-in-Place Foam Blaster

A print-in-place foam blaster inspired by Working Cannon (Print In Place). The design can be found on TinkerCad here, and an video of a it being shot can be seen on my Twitter account

This is my first attempt at a print-in-place design, be warned it may not work all that well. 

To cock lift the charging handle up slightly and pull back until you can see the notch, then push down. To shoot pull the trigger.
