Who buys it
Home Assistant and ESPHome hobbyists who build devices but hate ugly project boxes.
The product
A 3D printed or laser-cut enclosure designed around a specific board, sensor and mounting location, sold as a file or as a printed part.
Why it fits vibe manufacturing
This audience already designs hardware and is used to buying files. A design sold as a file has no inventory and no shipping, and a printed version adds margin.
How to build it
- Pick two or three popular boards and sensors and model enclosures with named parameters.
- Print and test fit with real parts, including cable exits and heat.
- Sell the STL or STEP file; offer a printed version through a 3D printing service.
- Document the build in the playbook style and link ESPHome configs.
- Add variants for wall, DIN-rail and outdoor mounting.
The steps follow the 13-step playbook.

Risks and the boring part
Mains voltage inside an enclosure is a safety and certification matter. Stay with low voltage and say so clearly on the listing.
