Caleffi Radiator Valve Pin Adapter

thingiverse

I wanted to install a smart thermostat head (Fibaro) to my radiator. I noticed that mine is a Caleffi, which none of the included adapters work. I printed this part off: https://www.thingiverse.com/thing:4022121 https://www.thingiverse.com/thing:4674368 and that allowed me to screw on the smart thermostat head to the radiator. But, it wouldn't adjust as the pin is too short. So I quickly made a spacer that fits on it and now it works. I included different sizes, but the 8mm one seems to work for me. I printed it with the opening facing up and rafts as it is a tiny part and it adhered to the print bed better. I used PETG material which should be fine temp-wise.
