A mashup of a Bre Pettis head and a filament guide. Watching over his creation... After installing, rotate head 45 degrees clockwise or counterclockwise. If installed as in the picture, the chin hits the front left black frame when you initiate a print. Use raft and support. I printed this on standard settings with 10%, 2 shells, 0.20 mm. Mashed it up on Tinkercad.com: search Bri Pettis Filament Guide for Replicator 2
