Velleman / 3Drag Extrusion clamp

This is a small brackets that slides into the Extrusion of a Velleman K8200 or 3Drag 3D printer. Is allows an M3 nut to be inserted into the back and then an M3 bolt to be inserted from the front, allowing accessories to be mounted to the Aluminium frame of the 3D printer.

I would like to thank [BVD](http://www.thingiverse.com/BVD/about) for his model of the [extrusion](http://www.thingiverse.com/thing:424674) which enabled be to create this model so easily.
