Thanks for the design !
How could i tighen the screw between the roller and the motor mount ? The nut speen with the screw. Shoud i glue the nut inside ?
Thanks for your help !
Stick something pointy like a small screwdriver beside the nut. That should stop it from spinning.
As Jamie said, I think that the better way, I have used a small flat screwdriver that I put on the right or left (depend on the way it turn) of the nut.
it’s kinda tricky but it works (for me)
