Nice simple case for the USB-NeoHub by Olimex*.
There are versions with and without a logo.
The two parts are a pretty tight fit and is probably a good friction-fit (depends on your settings and printer) but you can screw it together with 2 M3-screws (you can threat it by screwing in a M3-screw). You need two 3 mm screws of minimal 10 mm.
Happy 8-bitting :)
