Prusa Mini Minda Saver (Cable Guide)

thingiverse

The Prusa Mini struggles with a severe case of bendititis in its X carriage cable, causing the Minda sensor wiring to break within weeks or even days after delivery. To mitigate this issue until a factory fix becomes available, this part significantly reduces the stress on the cable, thereby extending its lifespan. The wiring typically fails near the top tie wrap located at the extruder. The Minda Saver functions by repositioning the entire cable 15mm rearward and securing it loosely at a 60-degree angle with rounded openings. It replaces the original cable and is held in place using two of the standard-sized tie wraps at the extruder and one at the cable slot. The design allows for slight rotation, further minimizing the constraints on the cable. By reducing stress on both ends of the X travel, it offers a more reliable solution. If you find that the cable slips excessively downward due to the reduced clamping, simply add a tie wrap above the Minda Saver to limit slippage. When setting up this solution, move the X and Z axes manually to their limits of travel and verify the cable's freedom.
