Show and Tell

I've printed most of Steve's clocks, but I think the SP15 is the most beautiful!

It's not as huge as the SP14, which I also built, but it looks great in my studio.

I've attached a video of it running perfectly: I built it 8 months ago and it's never stopped!

Very precise, max a couple of minutes a week.

One small detail: it runs with just 2.5 kg on the pulley!!!
