2.5 g total weight (with supports).

It's best to use a 0.2mm nozzle for better quality. I don't have one, so I used 0.4mm. For the 0.2mm nozzle, I add a separate model with finer "teeth."

Supports are enabled. Note, separating them can be quite difficult.

Layer height should be as low as possible. In this project, I have a variable layer height: 0.2mm on the "teeth" and 0.1mm for the rest of the model (from 1.5mm to 5.5mm of the model's height).

I also enabled "fuzzy skin" to create a rough surface.
