Printable Eggbot Engraver Mount

This is essentially a remix of the pen lever and spring by Balthazar (thanks for those)! I found them (and a whole lot of other great ideas) on the Improved Printable Eggbot pages by NGlasson and Daniel Isdell.
This mount accommodates the elements of the Eggbot Engraver kit that can be purchased from Evil Mad Science: the vibration motor (shown separately in the photo) and the engraver stylus. The motor speed control sits off-board in the rear of the unit.
As a first test, it worked to engrave a light bulb. However, since light bulbs are frosted inside, it's too hard to see for a picture. Next I'll try a wine glass. I'll post those results later.
