A quick hinge I made for 2020 extrusion.
For each hinge you need:
1 - 40mm M3 socket head cap screw
1 - M3 nut
2 - M3 washers
4 - 12mm M3 socket head cap screws
4 - M3 T-nuts
Press the nut into the hexagonal opening in the smaller piece, then thread the 40mm screw through the same piece. Place the 2 washers on the 40mm screw, then place the larger printed part on the screw. Use the 12mm and the t-nuts to attach to the 2020 extrusion.
