I made this attachment for KalleKnall's gorgeus PSU brace out of my recently published terminal block. It allows you to extend the PSU cable of your MK3(s+) by means of a steady screwing terminal with no need to take apart the entire cable harness.

The design consists of a main part which can simply be pluged into the brace's lateral extrusion holes. It already features a very tight fit but optional screwing with two 30xM3 is also possible. The second part is a cover that can also be attached to the main part screwlessly. There is a tiny square hole on the main part's side that allows bridging individual terminals by inserting a 1.5mm² ( 1.3mm Ø ) solid copper wire which is commonly used in electrical installations. The main part additionally features some holes for cable relief. Optionally there is a third part that can be attached to the main part to provide cable relief for the opposing side as well. The main part in sum features eight holes for setting up a terminal for utilization reasons. Four of them are actually required in order to extend the MK3's cables. The remaining interfaces are spare and can be used for power distribution etc. Your own creativity is asked for ;)

Printing

Pretty standard: PETG or PLA, 0.2mm layer height, 0.4mm nozzle, 15% infill, 2+ perimeters. Supports are not required but you can enable brim if the thin walls of the main part cause adhesion issues.

Additional parts:

• For each favored terminal: 8mm pan head M4 screw + regular hex M4 nut (square nuts do not fit!) + 2x M4 (square) washers + “fork” cable lug
• 22-86mm 1.5mm² ( 1.3mm Ø ) solid copper wire (length depends on the number of interfaces you want to bridge)
• 2mm cable ties
• 2x 30mm M3 screws (if you want to screw the main part on the brace)
• 1.5mm² braid wire

Know issues:

• There is no applicable cover yet if the attachable cable relief is in use.
