DIY power distribution block:
During the rewiring of my MR2 I needed two power distribution blocks for my power management throughout the car. I was not satisfied with the availability and pricing of commercial distribution blocks, so I decided to make my own. The basic premise is a plastic shell which houses a brass core. The brass core has multiple openings for power in and out wires and the wires are held in place with set screws. The outer housing was designed in Solidworks and printed using a 3D printer. It has a removable lid such that the brass core can be inserted.
Two separate distribution blocks were made. The input/output holes in the brass cores were machined using a drill press. The first has a 1/0 Gauge input and 1/0, 2, 18 gauge outputs (for engine bay). The second has an 8 gauge input, and 8, 18 (multiple) gauge outputs (for cabin). The set screws were initially black steel, but were switched to brass for the final product.
