thingiverse
3D printable version of the makedo scru for attaching cardboard together. Tweaked the version by jepler to improve initial threading into the cardboard and to add a hole that fits a lego technic pin. This is suitable for attaching 2 thick (or 2-3 thin) sheets of cardboard together. You can increase the length in openscad to attach more if you want. Works with this tool https://www.thingiverse.com/thing:974158 and should fit any makedo tools.
