coaxis mounting bracket

The coaxis aluminium profile from Alfer is the one used by Velleman K8200 3D printers. I got it from http://modelltechnikdirekt.de and it is useful for many other things beside construction of 3D printers. This bracket is intended to be used for mounting one of these profiles to another one with a size of 40 x 40 mm. Of course there are various situations where this bracked can be valueable.
