Material plan

PETG / ASA

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

Starting setup

15% infill

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

Final totals

Confirm in slicer

Slice the selected model with your final material, orientation, walls, and supports.

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

Description

The original knobs on the radio all split down the middle, so after trying unsuccessfully to find more in various junkyards, I decided to design new ones and print them. After they were done, I put some white paint I had laying around and brushed some into the recessed line to see where it was pointing better. Each one only takes around 4 minutes to print on a slower speed, use high resolution, infill doesn't really matter. It uses the original tension clips that go on the knob post, so make sure you take them out of the original knobs or off of the post before trying to put them on.
