I wanted to have nice connectors for the extension of my MK3's PSU cables without having to tear down the entire cable harness. Since there were no proper screwing terminal blocks available out there, I did it maker style and designed my own. Measures were taken from my original black Delta PSU's terminal block. So dimensions should be really close to that.My design additionally features an optional part for cable relief that can be attached from the top on both sides.Bridging individual terminals is also possible by inserting a 1.5mm² ( 1.3mm Ø ) solid copper wire which is commonly used in electrical installations into the square holes on the sides. Fasting the screws will establish conduction thanks to the nuts.Printing in PLA or PETG at 0.2mm layer height with 2 perimeters, 15% infill and a 0.4mm nozzle should do.
