Geometric Hexagon Coaster with Molds

Hexagon coaster with mold models so that they can be made with various materials such as concrete and resin, or printed directly.

 

I use these to make concrete coasters. You can create silicone molds from the positive mold file or you can cast the concrete directly in the negative mold. I smooth out the molds by using a couple coats of bonding primer along with some generous sanding followed by an enamel paint.
