This model is especially suited for silver or grey filaments. In my case, I printed it with a turquoise PETG and then coated it with an aluminum spray can to give the model a nice metal finish.

Inside the folder, there are two STL files of the same knob. One has an M4 predisposition. The other can fit an M3 screw. In both cases, self-tapping screws are required.

Here's a set of suggested print settings:

Nozzle diameter: 0.4mm

layer height: 0.3 mm

perimeters: 2

Top/Bottom layers: 2
