The RoadRunner Bike Riding Device

thingiverse

I'm thrilled to finally release my Roadrunner bike device. Jimmy loved his first device so much that he wore it out, outgrew it, and asked for an even bigger one. Version 1.0 is Jimmy's very first Roadrunner device. It prints in two parts and fits most standard print beds. Version 1.1 is larger, comes with a longer socket, and prints in three parts. The socket and ring can be printed on a much smaller print bed (but the socket needs a taller envelope) and the print orientation makes the socket even more durable, less prone to delamination. The socket and ring fit together perfectly like a puzzle and are to be glued with a 2-part resin epoxy. The peg curls around more, making it easier to stand up on the bike without the ring coming off the peg. I strongly advise against printing in PLA or ABS! I printed version 1.0 in Bridge nylon, and version 1.1 in PETG. You will need to use a similarly durable material and ensure your print head is hot enough and your fan speed low enough (or turned off) to guarantee excellent layer adhesion. Support structures are built into the model, so you should print the components with no additional support. If you need files without the support structures, feel free to contact me. As it stands now, this device will fit some people just fine. You will need to modify the socket and/or ring to fit most people with a transradial amputation or wrist disarticulation. If you need help with that, don't hesitate to reach out!
