I purchased and hung this solar system in my son’s room when he was 2, and he loved it. Today I donated it to my STEM lab for my students and they seem to love it just as much 🙂
I built a simple, lightweight winch from an empty spool of 3D printing PLA filament, some 1.5″ PVC fittings, a bolt and some nuts and washers. The most expensive thing was the kite string, which I then waxed and ran through some eye hole screws. The whole thing cost about $8 and I have most of the string left over for other projects. The kids love that I can raise and lower the solar system 🙂
