Ribbon Shooter

As noted, this is a heavily modified verson of another Thingiverse model. It is designed to eject a higher volume of payload, specifically for our award-winning Gencon Costume Contest entry, viewable at https://www.twitch.tv/videos/2215082448 (Forward to 1:26:00 or so.)

Like the original, the ejection is powered by a spring extracted from a toilet paper roll holder. (The original model lists one source, but I don't think it's important). I also found the assembly a bit fiddly, and modified it - use an adhesive (we used JB weld) to attach the larger oval (back plate) to the spring and the body, as well as to attach the spring to the plunger. I imagine that you could use multiple springs - but we only used one.
