I've made a few different ones, when I built the fuge in my main tank I put tabs in the corners of the main chamber with 1/2" holes. If you keep parts from Maxi jets here are a few, zip ties or glue works. Any parts/pieces that are about 1/2"work
The temp probe is zip tied since it wont slide into a holder, I have this on both my setups
I raised these up for the photo
