Rapide Lite Extruder Guide for Flexible Filament

Tested with TPU, and it seems good so far.

For the filament feed hole, cut a few milimeters of your guide tube and fit it so it just clears the feed wheels.

I printed it at .1mm.

The photo shows a chunk I cut off, but I couldn't bear to take my extruder apart and print it again. The file here does not include the ned piece.
