Plastic 'Straight Metal Jacket'

Five-inch (12.5 cm) wide wall mounter - I wanted to mount some wall-mountable boxes laying around in a mess.

I have bought them years ago, they always slip down one from the other, from table etc. Now they are sitting gently on the wall.

The mounter is inspired by the http://www.thingiverse.com/thing:8356 straight metal jacket project.
