Instead of using screws, I wanted to use double-sided tape to install a Sonoff SNZB-02D in my dry box. So I added the 10mm mounting flange where you can easily put enough tape on.
I printed with PETG, 0.2mm, 15% Gyroid, support on build plate.
PLA is probably also fine.
The author remixed this model.
Removed the holes and added a 10mm mounting flange.
