Taurus Y Axis Remixed Front/Rear Idlers

thingiverse

jltx's design is great, no one can deny it. However, his pulleys started splitting apart on me, and rubbing on the alignment ridge built into the mounts. There was enough friction that I was getting small piles of plastic dust under my idler mounts, and I was concerned about the long-term implications for my belt. To resolve this issue, I have remixed the pulley as a one piece print which uses 2x623ZZ bearings rather than 1x608. I then modified the idler mounts slightly, removing the ridge that was used to keep the pulley pressed together, and integrated the spacer for the inner bearing race into the idler mount itself. I also shaved the top of the rear idler by .5mm to address the issue some have had regarding the Y axis measurement being slightly shorter than the Prusa firmware's accepted range. To install, simply print one of each idler, and two pulleys. Press a 623ZZ bearing in each side of each pulley, and follow the rest of the TauY instructions. I did briefly consider the possible need for a spacer between the inner edges of the inner bearing races, but I do not believe this should be necessary...and it would be a real pain to install. Just don't tighten the M3x18mm screw more than snug.
