Amoeba striker hop arm (nearing perfection)

thingiverse

My previous version of this was excellent, but it suffered one critical flaw. It was wider than the barrel cut out and while it would hop beautifully, it wouldn't allow for the use of super heavy bbs no matter how much you wound them - it would reach a point where it would make contact with the barrel and go no further. This version remedies this by using a simpler concave design. It's actually angled so there is the maximum possible contact area along the entire hop bucking (https://gyazo.com/321564b4c86f117cf9a95333caa7896c) and removes the sudden impact caused by the first part of the arm contacting the bb being very slightly higher than the rest of the arm due to angles. I've found even better consistency with this version than the previous iteration, however it does require more work and supports are needed unfortunately. If printed on its side there is minimal sanding required but still more than the previous version. https://gyazo.com/895da2e3845c73a0d2861fa27b148253 UPDATE I've added 4 new versions, one with a reinforcement to the section that makes contact with the hop screw and another one that doesn't have space for a compression nub. The other two are the same but with a contact area that protrudes out more (these two are untested and might be at the wrong angle). Disclaimer: This is designed for the stock hop up chamber and isn't a standalone part - it requires something compressible and elastic to go between the hop screw and arm (this is true for the first two versions). It's designed for use with Maple Leaf Autobot and Desepticon buckings and compatible barrels. Use with other brands and barrels may vary.
