Parametric Y Plate Bushings, IGUS Style, for Prusa I3, and variants with Solidworks 2014 source

I decided to get fed up with those terrible, loud LM8UU bearings that are literally falling out of my Chinese-made ones so I created an all-in-one support brace unit by combining it with my IGUS-style bushings. Mine are printed in ABS plastic but I wish I had printed them in Nylon. The parametric parts let you customize the inner diameter as well as the number of teeth on the outer rim. For those without access to Solidworks 2014 or newer, I included a six-tooth and an eight-tooth version - I personally use the six-tooth model myself. This modification raises your print bed ever so slightly, taking into account that using bushings or bearings can leave little room for wear and tear, which could have put my expensive $22 rod in danger of getting scratched by the aluminum Y plate if it decided to wear down during printing when I'm not around. **Instructions** Print this support brace with 30% infill density and do it slowly at a speed of 20-30 mm/s for the external parts - you can print the rest fast. Make sure to apply grease as I used silicone-based lubricant, but silicone spray might also work although grease stays in place better and gets into the grooves smoothly.
