Small, but important update. I was asking too much of the all-plastic split pulleys for the slot car axles. After some adjustments, I was able to fit a square nut into the pulley. This gives the pulley a lot more holding power without the risk of stripping the plastic with the set screw. The model files on Printables have been updated, and all machines/kits shipped from today will come with these new pulleys. There is one for 3/32 axles, and another for 3mm axles, and both have identification markings on the model to more easily tell them apart before attempting to fit to the axle.

à la Prusa so must be a good idea
