Printed these out since I was unsure how they actually mounted on the controllers. Turns out the "bump" si on the wrong side for them to feel comfortable to me lol.
Since the source model is unavailable, I guess I'll try to edit the mesh myself. At least, there's a well-fitting base to start off with!
I had an intense amount of stringing due to super humid/wet PLA... I think I also need to start doing coasting...
anyway, turned out great and fit with zero issues! The only major issue is that it's super uncomfortable for me to use due to the bump being placed in the exact opposite area of what I want!
