I’ve been making ornaments for the kids in the family each year, and I wanted to incorporate gears this time around. This is a three-layer design made of stained 3mm baltic birch, held together with snap pegs that also serve as axles. I made the gears on geargenerator.com, and I opened up the back so the kids could see how all the gears worked. After a bit of tweaking, they run pretty well - they are intended to represent twinkling lights on the tree
You really geared up for Christmas! Those snap in place connectors look like they could have a lot of applications as well especially as snap on hinges in boxes,
