Self bondage bolt for fiddle with rotating hand-holes

thingiverse

With this bolt remix of the fiddle by bababbak, you only have to guide the bolt through the holes from above. The anchoring folds down thanks to gravity once the bolt has been pushed far enough through the hole.You have pushed it through far enough when only the extension of the bolt is sticking out at the topYou may have to wiggle a little so that both anchor parts fold out. As soon as the bolt has been pushed through far enough, you can pull it up until the anchoring takes effect. After the session, you can push the bolt completely through the hole and you're done.I printed the bolt with PLA-CF due to layer adhesion but you can also print it with ABS or normal PLA.Attaching the two anchoring parts is pretty self-explanatory. You just have to clip them onto the two rods. This design is pretty sturdy as the anchoring parts support each other as soon as they are unfolded. Without the help of tools it´s very hard to break the bolt. - Always have a plan B for emergency situations.Have fun!
