Danfoss thermostat adapter ring

Adapter ring for Davolo Danfoss thermostat - my friend has bought thermostat but adapter ring was missing - couldn't find a replacement so I designed it.

On the picture, from the left - original adapter ring, thermostat with adapter ring and adapter, and printed adapter ring (previous version, uploaded one is better).

I printed it using PLA, 100% infill, 0.1 layer height
