This is the CORE One L companion model to the CORE One Pins Mod. It brings the same pin-based idler mounting upgrade to the Prusa Core One L, replacing the standard M3 screws for idler mounting with precision 3mm steel axles.

GT 1.5 and the Gen 2 Upgrade: Do I still need this mod? 🤔
This mod is 100% compatible with the recent GT 1.5 upgrade made with the 🥰 CORE One L+ Gen 2. It works in the exact same way as before and addresses the same weak points in the XY gantry system: idler play, mechanical looseness, and it provides general improvement of overall kinematic precision. Check the CORE One Pins Mod (Gen 1, Gen 2) model's description for details.

This model contains only the two XY motor mounts adapted for the CORE One L. All other parts — the XY carriage, belt tensioner pulley, spacers, and tools — are identical to the original CORE One Pins Mod ...and the same is true for full assembly instructions, print settings and BOM.

Happy printing ... and don't forget to leave a ❤ Like!
