This compact enclosure is designed to house both a relay board and an ESP32-C3 Mini. The base and endcap feature wire passthrough holes, with one sized perfectly for a USB cable. The ESP32-C3 Mini is mounted to the side of the relay using double-sided tape for a snug, low-profile fit.
The default box length is 75 mm, but I included a STL file can be easily scaled in height to accommodate different setups (in that case you will need two endcaps). For fast, efficient printing, the design supports vase mode — provided your nozzle is large enough to produce a sufficiently thick wall in a single pass. (I used a 0.8mm nozzle)
