Double Pendulum [clamp to desk]

Hi! This is my first thing, but I'll be uploading more soon.
It's my attempt at designing a double pendulum.

The concept: This is a simple contraption illustraiting the beauty of chaotic motion.

It is ment to be mounted on your desk with a lamp/furniture clamp, or a wood clamp (or any other clamping mechanism in this regard).

What you will need: 2 - 608 (skateboard) bearings (optionally a third one as counterweight), the allready mentioned clamp and (depending on your print) hot glue.

IMPORTANT: The clearence between the bearings ond the printed parts is 0.2 mm, but comment below if you would need an other vlaue, for the pendulum to work.

To set it in motion: Grab one or bothe arms, giv it a litle spin, and watch the magic happen.

The hole thing at rest is 30 cm (300mm) tall, and it can extend up to 55 cm while in motion.
