Filament Sharpener (for Easier MMU Insertion)

This model can hold a Faber-Castell sharpener and catch the filament shavings when sharpening.

Setup: Simply insert the sharpener into the hole and screw down the lid.

Usage: To sharpen the filament, insert it through the hole and twist the sharpener. Twisting the filament itself can be difficult, as it tends to bend and slip between your fingers.

I recommend using the flat surface of some pliers to lightly grip the filament near the tip. This makes it easier to twist the sharpener around the filament.
