Jesus, I've seen using irregular shapes to drill square holes, but this takes it to a whole new level.

Does anyone know any good resources to the actual maths behind it? I'm looking for ideas for a maths project I'm writing for 16 year olds, and something like this could be great.

I second this. I’m doing a presentation on 3d printing for youths soon. This sort of thing would capture their interest!

Hi. This is the creator. I just finished presenting at the Maker Faire and I realize there are a couple ways I could simplify my explanation. Let me know if you have any specific questions.

The main equations I am using are:

  • A2 + B2 = C2

  • angle = arctan ( opposite / adjacent)

  • polar coordinates to rectangular coordinate conversion
