3D Models

All parts are designed in build123d with custom helpers. Source notebooks are in the cad/ directory.

Printing

The models are designed around my Voron V2.4 printer. Other printers should work, but tolerances on snap-fits and clearance holes are tuned to my machine, so some adjustment may be needed.

Material: ABS is recommended for durability and dimensional stability. I use filament from TM3D Filament (no affiliation).

Slicer: All parts were sliced with OrcaSlicer.

General settings: 0.15 mm layer height · 3 wall loops · 15–25% gyroid infill.

Orientation: All parts should be printed in the orientation in the step files.

Case

2 wall loops is sufficient. Set outer wall width to 0.4 mm — required for the slicer to handle the antenna cutout geometry correctly. Seam position and seam scarf/gap settings may need to be tuned to hide the seam on visible faces.

Encoder knob

1 wall loop. Use a concentric top surface pattern to give the concave top a smooth feel.

Slider knob

Body: 1 wall loop. Use an aligned rectilinear top surface pattern with infill direction set to 0° — this makes the knob divots noticeably smoother.

Inserts: Print flat. Use 0.12 mm layer height and a very slow print speed — these are small precision parts and quality matters here.
