Breadboard Mount with Power Terminals

Update 10/9/23 - I added knobs that have a “+” or “-” indicator on them. This may be helpful if you're not able to print them in red and black.

This breadboard holder has power for both rails which can be powered with different voltages if needed. They share a ground for stability.

Build instructions

• Layer height doesn't matter
• Add supports on build plate unless your bridging is really good.
• I printed in PLA but doesn't really matter.

I used M3 screws for the terminals with washers underneath to hold the wires. They screw right into the red and black knobs.
