SONOFF ZBDongle-E protective case with USB extension slot
A wraparound sleeve for the SONOFF ZBDongle-E Zigbee coordinator, which measures about 65 x 23 x 12 mm including its USB-A plug and carries an SMA antenna connector on the opposite end. The sleeve is 71 x 29 x 18 mm with 1.6 mm walls, open at both ends so the USB plug and the 5 dBi antenna pass through, and it grips the dongle on internal 0.5 mm ribs. A slot on one face exposes the status LED and a 4 mm hole plus a screw slot let you hang the dongle on a wall at the end of a USB extension cable, away from USB 3.0 interference. Prints flat with no supports.
A sleeve sized to your exact dongle and mounting spot beats a general download. In SpeakCAD you describe it, preview the case free in the browser, ask the chat to adapt it for the ZBDongle-P or a ConBee, and download the STL when it fits.
