About this 3D model
Washer sized specifically for use on the Rostock Max CNC U-Joints on the Cheapskates incase yours havs too much play like a couple of mine this washer inserted the Axle Rods in the loose one's will tighten them up a bit. Depending on how much play you can sand it a bit if it's too thick or stop the print halfway through. I adjusted size to compensate for shrinkage of ABS so it fits Created with Customizer! http://www.thingiverse.com/apps/customizer/run?thing_id=41520
