Building a Pendulum Snake

I've built a pendulum snake (AKA a pendulum wave). I was always intrigued by this type of demonstration and decided to finally figure out what's going on there and build my own compact version.

I saw many designs with just a horizontal pendulum holder and the pendulum are adjusted to have different heights (this for example), however I wanted to design my version so that when precisely tuned, all pendulums are the same height from the base. In order to do so I did some math and designed the pendulum holder accordingly.

Here you can find the plans and templates

This is the spreadsheet I used to calculate the strings lengths
