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 have an eyelet attached so that it can be worn as pendant. In each orgone piece there's pointed quartz crystal with coiled braided copper wire, aluminum shavings, shungite powder, and some other crystals, like lapis, tiger eye, amazonite, jade, agate, jasper and such. Merkaba design was mixed in from this thing: https://www.thingiverse.com/thing:2618496 If you are new to orgonite - it's a great way to increase well being, protect yourself from harmful EMF, help plants grow, seeds germinate, wishes materialize, negative energy turn to positive, sky clear up - you get the idea. Here are some good resources to get you started:

Of course, do your own research, just beware that there seems to be some censorship with orgone/orgonite, so use DuckDuckGo or Presearch for better results.
