Radrunner Throttle

thingiverse

This is a thumb throttle attachment for an ebike that has a twist throttle. Just get three m4 screws and nuts 10mm or less and attach the throttle. There are two versions: The simple one in which you don't mind the screws being seen, and the version with covers that you can attach using superglue or hot glue. I printed mine at 100% infill and .24 resolution. But any combination will probably work fine. It's up to you. NOTE: I glued a thin piece of rubber under the plastic throttle before attaching it. Gives it more grip. They sell thin, foam rubber sheets at any arts and crafts store, including Walmart for about a dollar.
