FRITZ!Box 6591 Cable - 10-Inch Rack Mount Shelf

Printed at 50% infill in Prusament PETG Galaxy Black.

I cut it in 2 pieces in the slicer to fit the bed and will probably glue the top on. Or not. We will see. 

It will print without supports if you dont mind minor cosmetics on the side-support for the router. 

Added a “stop block” which will hold the box in place. Can be glued in or will just “press-fit”.
Disclaimer: I only printed a segment (see fixblock.m3f file) and that was enough for my purposes.
