About this 3D model

This is my first Version of a Grinding Bed for my [Ultimaker Dremel 400 Grinding Head and Holder](http://www.thingiverse.com/thing:222543). I will improve this a bit more, because the PCB is just placed in there, and i may eventually pop out or not fit. This was just a quick first version to make some tests with my new head. ####Status: working but needs improvement. pcb-machine.h contains the settings i used for [pcbgcode](http://pcbgcode.org/) ####TODO: Add some clamp stuff to fix the PCB better
