All three parts are designed to print without supports as oriented in the stl files:
- Wall mount, wall face down
- Case, closed end down
- Lid, outside face down
Etherten board slides into slots and is held in place by the lid. Lid is affixed with four 10mm M3 bolts (total overkill, just for the looks). There's space for a shield too.
An extra hole has been added to the lid to run a cable out to a temperature sensor for my project.
Case simply slides into the wall mount. Designed to be placed on the wall with the curved sides horizontal to allow for air flow through the slots. Board doesn't get that warm, so probably doesn't matter which way you orient it, other than lid facing down; otherwise, it would fall out of the mount. Wall mount is affixed to the wall with two countersink screws.
I printed it in a translucent blue PLA; looks good with the blue LED shining through it.
