Review on 🦋 Exquisite UGEARS Fluttering Butterfly Wood Puzzle: A Delightful Mechanical Masterpiece by Calvin Hodges

I love the finished project. It was very difficult for me to stretch thick rubber bands through the slots. My fingers hurt so much that I had to take a few days off to keep trying. Finally a success, except part of the shaft broke when I first started it. I had to glue it carefully. I also made a mistake with the rubber bands for the foot brake. I had to go back and redo that part. Despite the difficulties, I somehow managed to make the butterfly flutter. Use lots of wax and require lots of sanding. Make sure the toothpicks are the right length for the wings. I had to redo them. Watch the video carefully. I gave it 3 stars for the build but the final project gets 5 stars.
