Often when developing IoT use cases, sensors and supporting boards are readily available, but housing the electronics at the edge is a challenge.
Would it be possible to develop an easily scalable, (semi) professional case design that bridges the gap between early prototyping and high volume deployments?
- A base case-design with lasercut front and back and a 3D printed house
- A parametric implementation for automatic sizing to your specific PCB, battery holder, sensor, etc.
- Swappable back design: Table model, screw mounts, and DIN rail
Choose values for A, B, C and D so that your boards and/or battery holders fit, either vertically or horiontally, in the two slots.
- Connectors, (touch)buttons?
- Status leds and ambient feedback?
- External sensor bay?
- How to parameterize the SVG's (better)?
- Online version of the design generator
v0.2
- Smoother/parallel circles
- Better side thinknesses
- Use screws for fixing front and back
v0.3 and v0.4
- Smoother lines
- Support horizontal and vertical placement
- Parameterize towards PCB size + optional 2x 18650 battery holder
v0.5
- Testing support for melt insert nuts (Ruthex M3 Schroefdraadbus M3 x 5.7)
- Small irregularity in the design at top left corner of the case.
- Fixing the boards with a clip
| Board | A | B | C | D |
|---|---|---|---|---|
| Firebeetle 2 (60x25.4mm, 62mm including protruding USB connector) + 18650 Battery Holder (80x21mm) | 62 mm | 16 mm | 21 mm | 30 mm |
| Arduino Nano (45x18mm) + 18650 Battery Holder (80x21mm) | 60 mm | 8 mm | 21 mm | 30 mm |
Front and house are easy to mod. Front can be cut from plexiglas, but printing introduces extra modding options.
