This is Thing-a-Week #9, previous things can be found here. http://www.iheartrobotics.com/search/label/thing-a-week
This weeks thing is a positive master of a wearable badge designed for the Make:NYC Casting and Molding Lab. http://www.makenyc.org/?p=81
The badge is designed designed for maximum success for beginners learning plastic resin casting. Designed for a one part mold the included 5 degree draft angle on the surfaces insures that the part can be removed easily from the mold.
A pin back can be glued to the back so it can be worn to your local Maker Faire. http://www.makerfaire.com/
Designs and a positive master can be provided for other Make:City Groups looking at running a casting lab.

After printing the parts must be sealed with a clear coating. A clear spray acrylic works well.
