NODE CASE

Node Case is a small shell for a dev board. One button on top, vents on the side, and a gap between the halves so the board stays visible. We did not want to hide the electronics completely.

A board case is usually either a bare acrylic sandwich or a black box you cannot see into. While you are testing, you need to know if the board is getting hot.

1. 01

   Place it from the real mounting holes, not from a nice square drawn first.

2. 02

   Print the button cap on its own, with 1.2 mm of travel. Shorter and it triggers by accident. Longer and it feels like a toy.

3. 03

   Line the vents up with the chip, instead of spacing them evenly.

The first shells locked and would not open. We switched to short clips and left a seam so a finger knows where to split them.

A charcoal shell and a yellow button. The seam is part of the design: it vents, and it shows you where to open it.
