I designed, 3D printed and assembled "Christmas Tree, 2023" for my wife for use on our Christmas table, our granddaughter's dollhouse, and on my wife's nightstand. She asked that it be operated from a wall outlet so no batteries were required.
As usual, I probably forgot a file or two or who knows what else, so if you have any questions, please do not hesitate to ask as I do make plenty of mistakes.
Designed using Autodesk Fusion 360, sliced using Ultimaker Cura 4.12.1, and 3D printed in PLA on Ultimaker S5s.
