The file 'N20 Wheel 30, 32, 34, 40mm For Orings 3D Printer Model' is (stl) file type, size is 196.1KB.
Couldn't get any of the N20 wheels in either the right size, or so the D shaft would actually fit on the motor. Made several different sizes before I found one that would fit nice and snug, but not break the motor or your hand putting them on.
I forgot to add that you need to add your own oring to these. OD needs to be the size specified for the wheel (ie 34 wheel needs an oring with OD of 34)
