I have the cheap humidity and temperature monitor from Xiaomi laying around and I decided to fix it on my Ender 3 v2. However it should fit on any 20*40 v-slot profile. It also tilts the display 45 degrees to improve visibility.
Prints without any supports.
I printed it with PETG so it can withstand being inside an enclosure, but I assume a TPU may be a better choice for the task, as it is quite a snug fit for the display.
You need two M3x6 or M3x8 screws to connect two parts together.
The piece slides into the profile. Then you can optionally fix it in place with a screw.
