Found a great design that matches the barcode scanner I have (https://www.thingiverse.com/thing:3319788) but needed some extra spots to hold the Wireless USB dongle and charging cable when not in use.

Prints fine without supports (print bottom side down like the after shots).

Fits this barcode reader (and probably most others) 2D Bluetooth Wireless Barcode QR Code Scanner IS-5700DB (Yellow)
