Inspired by all the modded Makerbots and Mendels at the Makerfaire last weekend, I designed these mendel styled bearing outriggers for my rattly X-axis carriage. This slides super smooth and quiet and has definitely improved output quality, especially on tall prints. Mounting holes could be a bit better situated, but it works and doesn't bump into anything.
note: Small revision to the 180 piece on 9/29 - I added pockets in the reinforcement bump to accommodate the bolt heads.
11/11 I added files for the individual pieces by request
Use existing plastic bushings to center the parts when drilling and mounting. Pop out the old bushings before mounting rods. Tweak things with washers and screw tension so that the bearings are centered and just touching the rods, but not pushing on them.
