This is a mold to make the most desirable part of a chocolate bunny. If you want to make an entire bunny make http://www.thingiverse.com/thing:17507Enjoy...Print out both sides of the mold. You will need to brush the mold with acetone abs mixture so that the chocolate will not get caught in the crevices. You can use rubber bands to hold both sides of the mold together. Be sure to temper your chocolate. After chocolate is tempered scoop into plastic bag, and cut the corner of the bag off so you can inject the chocolate into the mold. Let harden then remove the yummy little bunny ear.For tips on working with chocolate see http://www.marthastewart.com/267061/tempering-chocolate
