simple mold of Doberman in profile with 8 degree draft. can be used as the positive for a silicone mold or with a vacuum forming system.
I used "Amazing remelt" food grade casting material (find it at Hobby Lobby) and made ice cube tray, then with food grade silicone made a chocolate bar mold. the photos show the printed model with Black PLA, then the results after casting in silicone. quite tasty chocolate bar!
