The original knob on my Klarstein mixer broke, so I decided to design and print my own replacement. This knob is made to fit Klarstein model 10008800 and is a complete drop-in replacement for the original part, with no modifications required.

For printing, the model only needs “build plate touching” support, which keeps post-processing to a minimum and makes it easy to print even on basic setups. I printed mine without any issues.

The knob has held up well in regular use so far and feels comfortable and easy to operate. Installation is straightforward: carefully press in the two tabs with a pair of pliers and then insert the knob onto the shaft. Doing this first makes insertion much easier and helps avoid stressing the plastic.

Overall, it’s a simple, practical replacement if your original knob is broken or missing.
