A small enclosure/case for a DIY Knomi v1 using standard off-the-shelf parts. Has pass-through buttons for easy access to the reset/boot buttons and works with both USB-C and MicroUSB devkits. Requires zero supports in the orientations provided.

 

The original model had the base shape down, but it had some issues:

  • The standoffs for the dev board were too shallow to accommodate M3x8s (the smallest screw that most people reasonably have on hand), the holes were slightly too small, and there were printed threads (printed threads just don't work for M3 screws, the teeth are too small at FDM resolutions).
  • The clips that attach the front of the case to the back are small enough that if it were to get bumped, the front would fall off.
  • The screen was 90º from the base, making it hard to see unless it was placed at eye level.

I've fixed these by doing the following:

  • Completely redid the standoffs (larger hole, self tapping, deeper)
  • Added four additional screws to hold the faceplate on
  • Added an angle to the base so the screen is facing slightly upward
