Hi,

Just a comment. In my iBoardBot set, the hole for the ball bearing in this wheel is a little too big (the wheel on the boards left side for use with x axis belt):

35
37

The ball bearing will not be tight enough, so the wheel will be wobbling and the x axis belt will fall off quite often. Especially when erasing.

I fixed it by putting a little tape around the side of the ball bearing so that it fits more tight. Maybe at glueing solution is better (without damaging the ball bearing).

best

Torben.

Hi Torben!
We will modify that design so you can print it using any 3D printer (there is sort of “tolerance” when printing with a 1.75 mm diameter filament instead the 2.85mm and different batchs of 623zz bearing are slightly different). We will post the new design as soon as possible. We have already created one but we will need to test it with printers with different nozzles sizes (0.3,0.4 and 0.5 mm). I will leave it here, in the meantime (attached)
