circo thermostat adapter

thingiverse

This is an adapter that fits on the circo valve used for central heating radiators. It converts from the non-standard press fitting into a 30 mm screw fitting. I use it to attach a danfoss eco 2 thermostat. Print the two models and screw them together with two 3mm screws (20 mm long) and two square bolts. These screws are commonly used in DIY 3d printers, that's why I have them lying around. You can also modify the model to use other screws. This can't be printed in PLA, as it can't withstand the heat of the radiators. I used PETG, but ABS will also be fine, I guess. The threads of this model is stolen from another model, I can't remember which. The rest is new design.
