I have several of these Microclimate Evo thermostats and have stuck some to the vivariums but for my biggest vivarium I wanted all the electrics together on top. I couldn't find anything close to what I had in mind so I made this on Tinkercad. It's my 3rd attempt at designing.

I designed it to be printed on its back with no supports and hopefully no weak points to cause a failed print. Mine printed on the first attempt without any issues. The screen presses in with a little friction, just enough to hold the screen without the need for any adhesive.
