Metric nut tools

When I assemble electronics, e.g. attaching a PCB to a mounting plate, I often miss a small nut tool as a wrench often is to big and to clumsy to mess around with. Hence I made this small set of small finger nut tools, that helps out with the problem. The sizes are 2.5mm, 3mm, 3.5mm, 4mm and 5mm. The holder is just to keep the nut tools together.   The holder.stl and holder_embossed.stl files are meant for multi-color printing, but only Bambu Studio (at the moment) can detect the 0.05mm protruding numbers in the holder.stl file, so for other “Orca Slicer” derived slicers, you can use the holder_embossed.stl file, as the 0.1mm embossed numbers seems to work better in other slicers. If printing in a single color, either files will work.   Here printed on an A1 Mini using generic white, black and red PLA filaments with a 0.4mm nozzle and 0.2mm layer height.
