Nest Thermostat Gen. 3 wall plate. The rectangular white one that came with it didn't match my wall very well. Designed in Freecad. Printed with Hatchbox Wood PLA filament. 205°, 25% infill, 4 top layers. Printer: Monoprice Ultimate with Micro Swiss hotend. I have two stl files in this project. nest_wallplate.stl is 150mm in diameter, and nest_wallplate_170mm.stl is 170mm in diameter. I also uploaded the Freecad source in case someone wants to customize it to their own needs.
