Hex nut helper M5 (DIN 439 hex nuts) for 2020 aluminum extrusions with 5mm slot

thingiverse

I needed black aluminum extrusions, but in Germany, where I'm from, black extrusions come with a 5 mm groove only. That's why M5 hammer nuts won't work because they require a 6mm groove.\r\n\r\nThis is my budget-friendly workaround: print this helper and press M5 hex nuts with half height (DIN 439) into it.\r\n\r\nI've attached the Freecad file so you can modify dimensions if needed.\r\n\r\nThese helpers worked for me, I used hundreds of them for my Hypercube build. I printed them in ABS.
