Hauck Alpha Riser

I noticed that the legs of the Hauck Alpha high chair have different angles. I couldn't find an online model that took both angles into account. That's why I designed my own model. The riser adds 5cm in height. I also added recesses for felt glides to protect the floor. The felt glides should have a diameter of 20 mm. There are no sharp edges. The risers sit tightly on the legs. Strangely, one leg of both of my chairs is slightly thicker (19.5 mm). I suspect this is due to the paintwork in this case. In this case, the riser needs to be adjusted slightly with scaling.
