Prusa MK2.5/MK3 Filament Sensor Cover Upgrade

thingiverse

When unloading the filament, it sometimes gets stuck, making it tough to remove the jammed part without dismounting the filament sensor cover. I created a two-part cover design, consisting of a fixed piece and a removable screw-in section that holds the PTFE guide tube in place. To fix a stuck filament, simply unscrew the top tube holder and you're good to go. The Festo version utilizes a PC-4 M6 pass-through coupling. In this setup, the PTFE tube replaces the shorter 13mm tube and works seamlessly with MMU 2.0, providing a smoother filament path. For assembly, reuse the kit parts and follow the provided photos for a hassle-free experience. If you find this helpful, please consider showing your appreciation by liking or tipping. Added features include: Festo PC-4 M6 compatibility for MMU 2.0 and Bowden configurations (added December 30, 2018) Also compatible with MK2.5 upgrades (updated July 22, 2018) Thread fit has been relaxed for easier assembly (updated March 15, 2018)
