Tacx Neo shim: solving the grinding!

Having problems with your grining Tacx Neo (1 and 2) and even installing a third o-ring did not solve the issue?

Print this, take a single o-ring of your already installed o-rings and put it on the axle facing the o-ring inwards.

One version is with tiny discs on the bottom to increase adhesion on the bed

printed my shim as following:

o just one piece

o PetG (PLA will not work as it gets warm inside!)

o 85% infill

o 0,2mm layer

Take care to not tighten the dropout screw too much: hand-tight will do the job too!
