This model is a replacement wheel for ABB time dimmer switches. It is intended for situations where the original plastic knob is damaged, worn out, or missing.

The model was created to closely match the original shape and provide comfortable manual control of the dimmer. It fits directly onto the dimmer shaft and allows smooth adjustment of the timer function.

Recommended print settings:

• Material: PLA or PETG

• Layer height: 0.2 mm

• Infill: 100 %

• Supports: not required

• Print orientation: flat on the top surface

Depending on your printer tolerances, you may need to slightly adjust scaling or clean the shaft hole after printing.

This part is not an official ABB component. It is a community-made replacement designed to extend the life of existing devices instead of replacing the entire unit.
