Prusa MMU2/S Reinforced Idler

thingiverse

This is a bespoke Prusa MMU2 idler with some alterations.\r\n\r\nAs I've disassembled 2 of the original ones and encountered some difficulties with idler bearings being slightly too loose, I've designed this in Fusion based on the original. Fit and size are identical.\r\n\r\nThe modifications are:\r\n- enhanced shaft connector (no more cracking)\r\n- broader channels running lengthwise (simpler disassembly if needed)\r\n- tighter bearing channels \r\n\r\nCAUTION:\r\nAs the shaft connector part is sturdier, you'll need slightly longer screws. M3x12 from the MMU2 spool holder fit perfectly, but verify if you have enough clearance to rotate the idler before turning on the printer!!!
