i have printed an omniwheel to use in my robot

problem is, i noticed that during the rotation, the wheel is "floating" for some period, i have marked the problematic region ,

i tried to put isolierband there, but it's not solving the problem in 100%, and the trade-off is the movement of the little wheels.

i noticed that the problem might be the part that cis connected to the shaft.

is there anyway to use this wheel? i want to avoid reprint it.

If the two rollers with red

If the two rollers with red ink are “floating” as you say, maybe you could lightly sand the roller that is between them on the opposite side. My guess is that is what is making them float. Without any give in the wheel itself, the dimensions need to be pretty precise to get a wheel functioning as good as a factory made version. Good luck.

I assume the wheel is now working? :smiley: Nice job!
