Case for mechanical 7-segment display clock

Case for: Four mechanical 7-segment display units, published at https://www.thingiverse.com/thing:5066794 -- An excellent design by https://www.thingiverse.com/shiura

The case and back cover are each printed in two parts on a single plate. The parts are glued together to complete the assembly.

No holes for mounting back of case or display units. I just drilled holes slightly smaller than the screws I used. I used double sided tape around the interior ledge of the case to hold the display units.
