BluButton 3D Printable Case

This 3D printable case was designed for BluButton, an open-source BLE button transmitter project:

BluButton is part of the same ecosystem as BluButtonBridge, the companion open-source project that receives and integrates its BLE button events:

The enclosure is built around a Seeed XIAO ESP32-C3 with native battery support and is designed to fit a 503035 rechargeable battery. It includes 4 buttons, 1 event feedback LED, and support for an external whip antenna for improved wireless performance.

BluButton is based on encrypted BTHome advertising, optimized for BluButtonBridge, and designed to remain compatible with generic BTHome consumers such as Home Assistant. This makes the project a

practical mix of 3D printing, embedded hardware, and open-source home automation.

update v4

Added a structure to allow the buttons to be fixed without glue.

Use the ESP32’s included pin headers, remove them from the strip, and insert them into the holes of the structure after placing the switch.
