I'm not brave enough to leave this in our block of flats for 24 hours, so I asked a friend to do it for me. It's quite nice, though. I was really looking forward to showing it to my son because I knew he would love it.
Unfortunately, the steel marbles I have ready are about one millimetre bigger in diameter. I will therefore have to try printing some marbles or searching shops for suitable ones ASAP. To be honest, I am also quite keen to see it working.
