Compact Progress - 3D Printed Molds

I designed a couple different size molds for my compact's insulation... There are slight variations that account for the shrinkage that occurs during 3D printing and the shrinkage of the neoprene.... The molds are super simple, but if they work, I may think about creating more interesting molds to cast into.
I'm using a neoprene that I brought through critical coatings. It says on their website that painting the neoprene on is an option for creating a mold, this is something I might consider when doing the final piece and/or future pieces.
