Summary

A bare minimum Bus bar mounting system.

There are two different designs:
L bracket
Flat

which in turn offer 2 options:

1. Completely 3D printable but cannot withstand as much abuse

2. The critical "pillar" has been replaced with a screw, which in turn should give you more options for 3D printing it.

   NOTE: You require at least 2 parts per bus bar and even more for longer ones

ATTENTION: This design is provided as is, your use of it is your responsibility, the design doesn't offer any protection to the user from touching the exposed metal, use with care if you are using it with high voltages (which you shouldn't buying a proper part for dangerous Voltages/Currents is advisable).
