Improved X axis ends to replace stock ones on Prusa MK3S+ remixed from Prusa Bear proyect parts. All features of Bear design:
- Improved stiffness
- Reduces “toolhead pitch”
- Keeps bearrings in place and prevent them from spin
- Easier belt tension adjust
- Idler end has holes to screw 30-40mm bolts that allow to push off the steel rods for disassembly.
Bear proyect mods:
- Stepper and idler mounting points relocated to fit stock toolhead carriage.
- Added a groove to idler carriage that allows using a M3 bolt without snapping off the head.
Direct replacement of stock parts.
PETG recommended. PLA IS NOT SUITABLE!!!
