Hygrometer/Thermometer Holder for Hermit Crab Tank

I wanted to get my gauge off the ground, and figured I might as well make it look aesthetically pleasing while also giving my son's crabs something to climb around on.  Uses a round guage with a 41mm diameter rear insert.  I got the one from bambu labs for about $3, they can also be found on Amazon.  Model will need some supports along the tube that the gauge fits in.  I suggest paint on supports so it doesn't go crazy with the voronoi pattern.
