MK3 horizontal Steel Sheet holders

Some horizontal holders for the MK3S steelsheets.
Originally designed for a IKEA LACK enclosure but can be used under any surface.

Left side has the name of the steel sheet on it, right side is the same for every sheet; but has two variations: one perfectly fitting a LACK table and one generic version.
Stack as many as you like, or as long as your screws are.

Assembly is straightforward, put 4 M3 nuts in the top pieces, then screw them into place. After that add the other pieces with M3 screws from the bottom (M3x14mm for two setsor M3x20mm for three sets)
