Hi, I absolutely love my P1S ever since I got it last christmas, but I hate that it doesn´t have the chambertemp-sensor like the X1C, so I added it myself. It now shows temperature, relative humidity, dew point and vapor pressure difference - if you ever need that (Sadly it doesn't show these on the software of the printer, you have to use the Govee Home app and bluetooth, but good enough for me. You could also integrate it into your home wifi with their wifi gateway and monitor the temperature everywhere, but I didn't want to. Also NOTHING here is a product placement or an affiliate link, I'm just amazed how good and accurate these sensors are)

Before buying the thermometer you should check if the bracket works for your printer (I only made it for my P1S and I'm not sure if it fits all or the P1P)

You can use my provided testprint for this, just place it in the holes on the frame and see if it fits! (m3holetest)

Bill of materials:

1x GoveeLife H5100: https://amzn.eu/d/5ucRN2c 

2x (or 4x) M3-Washers 1mm thick - made from nylon or print them yourself with PET/G, Nylon or ABS/ASA - https://amzn.eu/d/3csN7BL

2x M3-Screws 10mm (8mm should also work but 10mm is easier to assemble) I used cylindrical caphead screws in black - similar screws to mine on Amazon https://amzn.eu/d/bqcnlP6

2x M3 Nuts (also included in the product from the link above)

Heat resistant filament - PETG should work and I printed mine with it, but you can also use Nylon or ABS/ASA

And some thin double sided tape (I used ~0.2mm thick tesa)

Assembly:

After checking the mounting holes on your printer, printing the thermometer-frame and checking the fit with the thermometer, you can start by putting the tape on the removable back and bottom side. (the side with the two small slots for the temperature sensor of the thermometer, without covering them up)

Then you can press the thermometer into the 3D-printed case (you have to place it into the holder with the open side at the bottom lining up with the small slots of the sensor)

Now you can place both M3 screws with a washer onto the frame and start screwing them into the holder until they turn through the material, then you have to push the other two nylon washers from below onto the screws (this step isn't neccessary and a bit tedious, but helps to mitigate the 3D print from splitting, if you turn the screws too hard at the end)

It's very tight to squeeze your fingers in, but I made it this tight to get better temp reading because the lower the thermometer is the lower the temperature gets and this height is the best tradeoff between good readings, small formfactor and still some space for your fingers while mounting.

After that it should just work and provide amazing detailed analytics for your 3D printing!
