Casing for 3D-Print-hardware MKS-(S)-GEN L

This is a case for a MKS-GEN-L-Board (or a MKS-SGEN-L). It has big holes on the four sides for the cables to get in. The cap has holes for a 80mm-cooling-fan that has to be put on the outside.

This case is there in four versions:

a.) Case with german text on the holes, nuts can be inserted during
b.) Case with german text on the holes, nuts can be placed after printing
c.) Case without text, nuts can be inserted during print
d.) Case without text, nuts can be placed after printing

The freecad-file is added, containing all versions, its constructed completely parametric, a spreadsheet named "aaa" contains all values.

The insertion of nuts while printing needs a printer that understands M600-command, and your work inside the slicer to add a M600-command when the holes for nuts are rey to be closed (was layer 30 for me, with layer-size 0,24mm).
The versions for nus to be placed after print have complete hexagon-holes from the start of print.

The text over the holes describes what should be connected here.
