Hi everyone,
I recently managed to pick up a rotary tool for pretty cheap. The only place that sells firebrick around here is Menards. I do not know if it is K23, but it was the only option besides online with shipping.
I got these ones:

I also bought this silicone (safe?):

This is what I have so far. I am probably going to deepen the cells some more. It has two openings for test tubes and/or air. I made those the exact size of the test tubes I use so they fit together. There is also one more opening to connect to an outworld. For now there is the separate cell for the water system. I am thinking of ways to have a longer lasting hydration system though. I'll test this out and go from there.
Figured I better share means I actually managed to make something decent this time
