Box for an Adafruit Feather nRF52 board to be used as a dongle (with permanently connected cable) Using a Feather nRF52832 board as a dongle requires a box where a micro usb connector is included. It consist of a bottom and a cover part. 4 screws (countersunk 2.2 x 10mm ) are used to close the box. The cabinet covers also the micro USB connector.
Cables are available in various executions – here I used a version with a 3mm cable. In case the connector is shorter, a cable tie can be attached inside as pull relief of the connector. The design can be printed in PLA or ABS. Fill 30%-50% Transparent materials make (the Feather) LEDs visible. Drilling the holes for the screws with 1.5mm ~ 1.8 mm is recommended before inserting screws the first time.
