Prusa MK2.5/MK3 Filament Sensor Cover Upgrade

IMPORTANT: Get the latest updates for this model here on PrusaPrinters.
In 2021, all updates and uploads of new models were moved to PrusaPrinters, of course still free and under the same conditions... :)

Sometimes the filament gets stuck when unloading - it can be difficult to get the stuck part out as you have to dismount the filament sensor cover.

I made the cover two part, a fixed part and a screw in part, holding the PTFE guide tube.

If the filament gets stuck, just unscrew the top tube holder and resolve.

The Festo version uses PC-4 M6 pass-through coupling - The PTFE tube will replace the short 13mm tube and works with MMU 2.0 giving better filament path.

For assembly reuse the kit parts and follow the photos.
