This is a project that I have been wanting to do for a while now. This is a rubber band Gatlin Gun that is designed after the hand fired Model 1874 Gatlin Gun. It can be fired hand held or on it's pedastal. 56-64 rounds! This is a work in progress. The assembly instructions will have to be developed. Supports: This project requires supports. The best type is PVA (water soluable) if you have a dual extruder printer.
