Levinson Choc case

This is a parametric two-part CAD model of a case for the Nyquist PCB rev3 with Kailh PG1350 switches and the undesirable bits broken off. Slightly slanted forward to accomodate TRRS jack cables.

Without cover

It won’t be a great hassle to adapt this for rev3.5. It will be able to lay flat in that revision, saving print time and material. In general the jack connector was a major pain point (though there don’t seem to be any USB C cables angled on both sides available yet).

You’ll need

Print settings

  • recommended is the default 0.4mm nozzle with 0.2mm layer height, quality settings

  • increase extrusion width for solid infills until the print looks clear enough (0.55mm produced a good result)

  • the cover looks better with right-angled infills

  • use the Hilbert Curve for the bottom fill pattern to make it look nicer

  • similarly recommended is a textured sheet for the heatbed

Both halves fit onto the Mini’s print area. Increase heatbed temperature by approximately 5 degrees Celsius if printing from PLA then, or otherwise make sure that corners don’t lift off. Increase the temperature mid-print to salvage if you see this happening, it should lay back down.

Issues

  • it may not match exactly, depending on extrusion accuracy

  • the cover parts stand in the way of MBK keycaps, and the right part likes to lift off at the far end, preventing full keypresses

  • screw holes in the cover need some fiddling around but generally work

  • Solvespace is slow at computing the cover parts. You can remove them entirely, they serve an aesthetic purpose.
