Rotary Knob for Daikin altherma 3 r ech2o heat pump
I designed the replacement knob as mine broke after less than 1 year, I created 2 versions:
The first has the same external diameter as the original but a little longer to make it easier to grip :
The second "reduce" version has a reduced external diameter when it comes out of the plastic so as to prevent it from breaking again with the weight of the heat pump cover.
Each version has 2 other variants with the "color" or monochrome "mono" logo
