Thinigiverse user Zamanlui’s copy of a Tiny CNC

Thinigiverse user Zamanlui printed a Tiny CNC with the idea to turn it into a platform for a phage/bacteria printer. While I realize that a two-axis CNC machine can be used for just about anything, I LOVE the idea that something this easy and cheap to build could be put to such noble uses.1 This makes me wonder…  what other potential uses would there be for a simple low cost CNC machine?  Here’s what I have so far:

• Phage/bacteria printer
• Drawing robot (one-off business cards, playing Tic-Tac-Toe, etc)
• Drawing electronic circuits with a conductive ink pen2
• Adding a third servo for a Z axis and a fourth servo for a gripper for a tiny sorting robot
• I guess you could turn one into a useless machine that turns itself off?
• Automatic pencil sharpener?

What other ideas can you think of?

1. Especially when my most noble idea is to make the ‘bot cheat at Tic-Tac-Toe [↩]
2. How awesome would it be to use a Tiny CNC to draw an electronic circuit used to power a Tiny CNC?! [↩]
