This is a small and easy casing for a Zigbee CC2531 USB-Stick as you can buy on eBay, Amazon and many other shops. The pcb slides into the upper part and is fixed with the lower part and two screws. Additionally I made a wall holder for it.

It should be easy to print, assemble and use.

Please note:

This casing is only for CC2531 boards with the short debug pins. Boards with longer pins will not fit into the casing - please check before you print. Please have a look at my images above and compare them to your board.
