Sharing what I've been working on the past few days. This is my TornadoBow. It uses the same design as pretty much all of them, except the plunger tube supports, trigger, catch, and spring plate are 3D printed. I've uploaded the files here for anyone who wants to recreate this. The plunger support plates are a friction fit, and shouldn't require much adhesive. The catch is designed for 1/2" Nylon rod. https://www.thingive...m/thing:2775832
I've also developed what I hope will be a solution to the problem of broken priming handles everyone's been having. Rather than a simple nub that attaches to the handle and creates a point where the handle will flex and snap, I cut a piece of poly that fills the entire void of the priming handle and distributes the load. It's also a friction fit, and I haven't had to use any adhesive to attach it.
