CNC-Egg(Plotter Ro)Bot Design with Modular T-Slot Base

I have long been enamored with the idea of blowing the minds of my nieces, nephews, and in-laws with robot produced Easter Eggs from an EggBot-type device.

Opportunity to make one of these semi-spheroid plotting devices from scratch fell into my lap when I adopted a nearly dead Mendle-style cartesian 3D printer. I took a look at the charred printer board, thought to myself that I don't like electrical fires, and stripped it for parts.

After reading about EBs for a while to gather an understanding of parts are needed and what features are handy/useful for adjusting the mechanics of the drawing operation, I set out to design one completely from scratch.

I did this for many reasons:
-First, because I didn't find any existing designs on Thingiverse with ALL of the features I personallly wanted
-Secondly, my collection of parts was somewhat non-standard
-Most importantly, I want to and it seemed like a fun challenge to re-invent a wheel.

If you have some of the same raw parts, I encourage you to use this, make it your own, and have fun printing/plotting.
