I bought a pack of three of these little bluetooth temp/humidity sensors/loggers for various places, and the first thing I learned was that the sticky double-sided included - wasn't. Well, it worked for a while, but when I had to change a battery cell, the device had to come off the surface it was stuck to, and that was that.

So I threw this together in TinkerCAD and printed it out, glued it to the surface with super-good double sided, and clipped the Mijia BT Thermometer into it. Easy to fit, stays attached really well, doesn't rattle, and easy to remove the device when needed.

It prints without support, needs minimum sanding edges in a few spots (but that may just have been my printer doing weird things) and for one of them I sanded the back of the mount and epoxied it to the location.

Stardard settings are fine or just do it at 100% infill for a really solid little mount.

Enjoy. Go to my Ko-Fi site if you find the case useful, and leave me a coffee or even join there. Also, you can actually BUY the STLs there for the price of a cup of joe if you'd like to help me out. I also do legit angelic good things with recycling, sustainable renewable green energy, EVs, and all sorts of hippie "peace, love, and environment man!" stuff you can check out my blogs and other links at Ted's News Stand and even sign up for a newsletter once a week. Lastly, you can even tip me on Paypal.

And it's true about the environmental hippie stuff - it's a mega-important topic we need to talk about - and I do, plus design cheap machines you can use to recycle plastic into useful things at home.

Peace out!
Ted.
