Bear extruder body with separate sensor insert

thingiverse

This is a dissected version of the Bear Extruder body that separates the component surrounding the filament sensor into a distinct piece. This enables the extruder body to be printed in any hue, and print only the part around the filament sensor itself in black. I printed them as two separate components in different colors, but they could also be used to print a single dual-color piece with an MMU. When I printed them separately, I didn't scale the insert at all, so it was a snug fit into the extruder body, requiring some assistance with a rubber mallet to get it into place. It's wider at one end than the other, so it needs to be inserted from the side with the extruder motor cutout. If you are printing your filament sensor cover in a color other than black, you will likely want to color the underside with a black marker.
