I hacked my hack of the Skadis folding bracket to make this a fixed unit for Multiboard.

Added in the 11-13mm socket labels as well.

The files are for fast/adequate quality 0.28 layer printing - this comes out reasonably well but you may want to change the layer height to better quality as you see fit. This will make the removal of the supports easier as well, but keep them as Normal/Snug/Baseplate only, unless you rotate the model to have the numbers at the front and then you can use Tree/Baseplate for minimal supports. This will increase the print time.

No supports are needed for the holes in any orientations.

Increase the infill if you want. Currently 8%.

There is one layer height modifier to change some of the number's colour/filament, the other numbers are coloured directly.
