3D Printed Breadboard

This work in progress has been a long term goal of mine, at least in the past year and a half that I have been involved in 3D printing. The recent release of electrically conductive filament has enabled some amazing circuitry creations to say the least.

What I have done is create a breadboard with a 3D printed conductive node. We know that we can print the nonconductive part of a breadboard, it's the electrical grabbers underneath that grab the wires that have resisted replacement, and this morning (July 11 2015) I realized that a simple wedge shape could replace the grabbers!

So I made a quick OpenSCAD model of a wedge that would fit and got some OK results. Each resistor had a 500 Ohm Resistance to a central low resistance node - makes sense I guess.

Then I printed a second wedge that fit better and was thinner and got very low resistance for the node for some unknown reason. Later this node opened up though, so I think it was loose.

In fact, I think what is needed is
