Print setup plan

Useful setup guidance without pretending STL byte size can predict filament, cost, or print time.

Material plan

PETG

Published material guidance; still check heat, UV, load, and printer compatibility.

Starting setup

25% infill

A planning starting point only; wall count, orientation, and geometry often matter more than infill.

Final totals

Confirm in slicer

Choose the needed variant, then slice it for grams, cost, and print time.

Saved setup guidance is used for material, infill, support, and per-file recommendation text; editable numbers are planning estimates only.

Description

Made a 50mm diameter knob and removed all gear numbers on top. Split the knob on the equator for easily print flat with PETG. I added a brim for extra security. Assembles with 3 little pegs with friction. Remix of https://www.thingiverse.com/thing:902091
