I wanted to have a stable holder for my folding ruler and a spirit level for my Skadis board, so I made these holders. The holders come in three different depths: 17mm, which fits a folding ruler, 25mm, which fits a spirit level, and 21mm in between, which is probably good for something else.
The holders is mounted on the Skadis board using a T-nut that fits M3 screws. T-nuts provide a strong and secure hold and are easy to install and remove by using a screwdriver. There are two different versions of the holders, one with countersunk holes and the other with flat holes, which one to use depends on the type of screw you are using. The screws that will fit should be about 15 mm in length.
Place the screw in the T-nut through the holes in the holder and screw it in until the T-nut is about 2-3 mm from the back of the holder, insert the T-nuts vertically through the Skadis holes, then as you tighten the screw the T-nut will turn and lock the holder to the board.
You can find and download the matching T-nut from: Skadis T-nut for M3 screw.

The best way to print the holders is flat on the bottom side. In the model files the parts are oriented in the best direction for printing. Use PLA for printing with a layer height of 0.2mm or less and a nozzle width of 0.4mm or less. A wall thickness of at least 3 lines and an infill of 25%. There is no need for a support structure.
