Lately the kids and I have been working on a Spirograph-inspired pancake machine called the Pangraph, which we use to make Spirocakes.

This device actually took some planning (as opposed to our Pancake Silly Maker 1), and the plans have undergone a few revisions.

I've put a lot of time into the plans for this project, so I'm charging $4.50 - send it via PayPal and I'll personally email the plans to you within 24 hours!
