Interested to know/connect! I've 3D-printed molds, smoothed them out, then applied mold release and poured silicone to make custom onaholes before. I don't have a ton of experience, and it's not like I can use TPE at home. But still super cool! I've also 3d printed some wacky stuff like an adapter to use a drill with toys. I'm currently planning to follow someone's build plans on patreon to make a robot stroker with multiple axes of motion and adapt it to use with onaholes. Just curious if anyone else does this kinda stuff haha.
