One of the kitchen faucet knobs came loose and could not be installed anymore. A plastic mounting clip broke and finally got lost. In the following picture you can see this part is missing in the upper knob.

Since a replacement clip would not be printable (FDM), a new knob was required. After using the new knob for a while to prove its functionality, the other knob was replaced as well for optical reasons.

Printing:

I printed the knob body in white Prusament PETG with a 0.4mm nozzle and 0.15mm layer height.

For the color dot I used Prusament PLA Blend in Royal Blue / Miss Pink, 0.4mm nozzle, 0.2mm layer height, concentric bottom infill pattern.

The dot was fixed on the body using superglue.
