The 3D-printed case is made up from 7 primary components.
On the rear face of the case:
1 x 1/4" - 20 thread
4 x M3 threaded mount points
M3 threaded mount points are available:
40 mm and 80 mm apart on the back
80 mm apart on the top and bottom
The 4 mount points on the back of the unit are provided by 3D-printed slugs of plastic with an M3 threaded hole in the center.
These can be used for attaching 'accessories' to the back of the WLAN Pi, or they can be removed and replaced with bar magnets.
The 4 threaded slug inserts may be replaced with Neodymium bar magnets.
The suggested convention is to install magnets with the North pole facing upwards, this convention would be used to make any future magnetically attached accessories compatible.
These magnets are optional, they do not come pre-installed. Magnet specs: 25 × 10 × 3 mm N52 Neodymium Magnets.
Available at and at all good Wi-Fi conferences.
