Summary

Simular to the Automatic Rubber Band Blaster-32, just bigger holding 72+ rubber bands. It fires ~7 rubber bands per second and can be instantly reloaded by swapping barrels.

Instructions

I recommend that you first print and build the smaller Automatic Rubber Band Blaster before you build this one. The loading is the same and the assembly is very similar, but you'll have to glue the top and bottom together with plastic glue. I don't have an instructional video for this one, but the wiring/ motor & button connections are the same as in the Automatic Rubber Band Blaster video below.

Uses #32 rubber bands
