Small box for the zigbee dimmer module taken from an IKEA Trådfri led driver, 10W.
Desolder the module after removing the casing from the driver, replace wires with some longer ones. Click-fit into the box and slide the lid in, clicking it in place.

With a properly tuned printer all parts should fit easily and require no tools. The dimmer module works well with 12V, as well as the original 24V when placed between a 12/24V source and LEDS.

Use at your own risk etc.
