Rapberry PI Model B+ bracket
This is the bracket to mount the Raspberry PI B+ to a 22mm pole.
You can download the model file from thingiverse:

You can download the STL file, but also the original openSCAD file, so if you are using different poles, you just need to change one variable in the openSCAD file and re-render.
