Tool to add or remove the internal nut for LK Systems Väggdosa. Consider it a printable copy of LK Unigrip V2 with RSK 1882695 https://www.lksystems.se/sv/produkter/universal/monteringsdetaljer/ovrigt/lk-verktyg-vaggdosa-unigrip-v2-77797690/

Model shown in picture is printed with 0,4mm layer height with 40% infill (cubic). You can print it in 0,2mm if you are not in a hurry as it will give a bit better results. I would suggest to print the top 8mm as a solid (can be adjusted in Cura via "top layers")
