This is a 3D printer attachment to a CNC machine that utilizes a standard caulk gun tube for producing 3D printed objects.

Here is a picture of the caulk tube extruder attached to my CNC mill.

Thanks.
It is pretty straight forward but the big sticking point for most people is that you need to start with a CNC milling machine that has the capability of running an extra motor for the extruder.

I swap my extra motor between my rotary table and extruder as needed. I would like to come up with more uses for the extra motor.
