Leveling leg (not only) for shoe cabinet

I needed a leveling of welded construction of shoe cabinet. It was welded from aluminum square tube 30x30x2mm.
Printed from Prusament PLA. Slicer properties: min. 3 perimeters, layer height 0,2mm, min. 30% infill, detect bridge layers, no supports needed.
Inside in insert is a hexagon nut M5, inserted when printing is interrupted using the command M600 at a height of 7.4 mm.
After printing, it is necessary to clean the hole above the nut using a drill bit of 5mm diameter (there is used a "bridge" height of one layer of 0.2mm). The foot is inserted hexagonal screw M5x25 (length is arbitrary) and the cover is sealed by super glue.
