  • I did it!
Yes, I built it, and I'm in my 70s. It was not easy for me. I wish it had included a few more screws because they get lost. Also, the springs were packed so tightly they were wound up in each other, and one sprang off so I needed to order more, which were really too thick for the purpose.

It was fun, but the screws were to tiny and we dropped them a lot. The lights also did not turn on.
