Prusa MK3 x/y adapter kit for igus RJ4JP bearings

thingiverse

Adapter set to switch from LM8UU linear bearings to IGUS RJ4JP-01-08. Target: - Make replacement possible without redesigning carriages, etc. - X/Y axis only; Z axis makes little noise and wear. - Avoid deformation on installation. - Keep X/Y axis geometry (endstop, etc.). X carriage: ------------- 3 washers on x Axis needed to eliminate play (2 top rail, 1 bottom rail) to eliminate x-axis play. 2 shims for x carriage needed (at my copy of carriage parts) - to avoid deforming the igus bearings and slightly increase resistance. Y carriage: ------------- Casing to spread force for firm mount and fixating y position in bed carriage holes. Keep ability to carefully adjust mount force via screws. 3 pieces needed for top and bottom part. Print without brim/support. Additionally needed: 6x M3x10 screw, 6x M3 nut square Print in PETG due to proximity to heated bed. Mount the bottom part with the indented side towards the frame (for the rod that holds 2; for the other one orientation does not matter). this is a work in progress. I'm still assembling my mk3. update 29aug18: added shims for x carriage update 15sep18: prints come out nice so far. No further modifications needed at the moment. On a paver in LACK enclosure it is really quiet.
