Prusa MK3 LM8UU Y Axis Bearing Holder Pillow Block with Nut Trap

thingiverse

Remix of a sleek design from Mimisb13 that eliminates the need for U-bolts holding the carriage to linear bearings on a Prusa MK3. Over-tightening can cause U-bolts to crush linear bearings and score rods, limiting their usability. This design helps prevent such issues by incorporating features that reduce the risk of damage. The updated version is identical to Mimisb13's original, but I added a nut trap for better grip when screwing in an M3 hex nut from above. For optimal results, print three of these parts in standard orientation.
