Box for 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. Can be printed in PLA or ABS. Fill 30%-50% Transparent materials make LEDs visible. Drilling the holes for the screws with 1.5mm ~ 1.8 mm is recommended before inserting screws the first time.
