Entering the third day, which was also the day the cello was completed, the most important part was the spring mechanism. If I hadn’t wanted to replace it, it would have been much simpler. Luckily, everything fit perfectly, and the result is fantastic. You don’t need to take the model out and wind the spring to make it work. Simply turn on the button and it’s ready to go.
Wow how pretty!! I haven’t seen this actually working before lol. It looks great!!!
It’s beautiful, and I love the colors.

Wow, that’s an impressive achievement! Replacing the spring mechanism sounds like quite the challenge, but it clearly paid off. It’s so satisfying when everything fits together perfectly in the end. I also love that you can simply press a button to make it work. That’s such a clever design. Congratulations on another beautiful build!
