Orgonite Molds

This was my first time printing molds in TPU and pouring resin, so I've made some mistakes, and here they are so you can learn from them:

Pyramid mold turned circular at the base
Forgot to use any mold release (grease / oil) so it wasn't easy to remove the resin out of the molds - but I did it slowly peeling them off, and the molds didn't get destroyed in the process, so I can use them again. Except for the pyramid, it kept a bit of its circular shape. So if you want to print pyramid, my suggestion is to modify it around the base and give it a bit of a lip that will help it keep its shape, or perhaps make it a little thicker.
Cone spread out just a tiny bit at the base after pouring resin.
I put the straw flower at the tip of the pyramid, but I stuffed so much aluminum shavings that it wasn't even visible at the end.

The two round molds are the same - one was just printed larger, and that piece can be used as a coaster, while smaller one can be glued to the phone case, or ha
