LM8LUU Bearing Blocks for Prusa Y-Axis

thingiverse

Human engineers have designed specialized blocks to accommodate the longer LM8LUU (8x15x45mm) linear bearings on the Prusa i3 aluminum Y-carriage. This innovative design features two M3 recessed screw holes, spaced precisely 20mm apart, with a precise key that fits seamlessly into the original hole where the bearings were formerly secured. If your Y-carriage does not have this particular hole but still has adequate 20mm spacing for the screws, you can easily modify a section of the .SCAD file to eliminate the key feature. Four M3 x 10mm screws and matching washers are required to securely hold the bearings in place, while two M3 socket head cap screws - either 20 or 25-30mm long - are necessary to attach the blocks firmly to the Y-carriage.
