Triple DC Busbar

Good quality busbars can be quite expensive, and most of them are of bad quality or completely unsafe. I made this one of a 20mm wide, 3mm thick copper flat bar, but you could go thicker if you have a need for it.  Mine is for summing 2 solar panels and would never see more than 30A. It should be printed out of some temperature resistant material. Mine is made out of the PETG. Connection spacing is 20mm.

Materials:

M8x20mm hex bolts (x3)
M8 nuts (x3)
M3x10 bolts (x4)
M3 nuts (x4)
20x60x3mm copper flat bar
