Prusa MMU Jig

thingiverse

This is the modified version of Prusa3D's MMU Jig that requires less metal components than the official one; a cooling tube and brass screw insert for pneumatic fittings are included, both with 6mm diameter for the pneumatic fitting tube and no need for brass screw inserts. All these features are available in three versions: v1: The filament pathway is similar to the original, allowing the use of Prusa3D's cooling tube as well. v2: A smoother filament pathway that doesn't require a cooling tube. v3: A square/diamond pathway. Interestingly, I encountered issues with v1 and v2 where the filament couldn't pass through the jig, but it worked fine with v3 featuring a diamond/square shaped pathway. There's a small chance that if you print v1 or v2 or the original Prusa3D MMU design, the filament won't be able to go through the jig smoothly, possibly due to filament sagging in there somewhere.
