This is a temperature and hygrometer (humidity) sensor mount for any 3D printer with a frame at accepts T-nuts. First version was for M3 bolts, added a new STL with larger screw holes for M4 bolts.

9-28-23: Added new mount for V-Slots, no metric bolts needed! For the v-slot version you will need to use supports, probably tree supports would work best.

I wanted to monitor the temperature and humidity in my print station and found a two-pack of these simple little sensors on amazon for about $6. They may be cheap, but I checked/calibrated with another hygrometer and they work great.

You can buy them from multiple vendors as they are a common design (As an Amazon Associate, I earn from qualifying purchases.):

You will need two T-nuts and bolts to mount the bracket. If you don't have any extra T-nuts and bolts, you can get a small kit of them here:

The sensors work well and slide in and out of the mount I made if you need to change the batteries. They come with batteries which will typically last almost 2 years (simple button cell batteries you can buy at the dollar store or on amazon).

Prints easily without any supports.
