Swivel Puzzle Box

thingiverse

This is a fun one, it requires a 3-5mm ball bearing for you to make the lock work. You need to first glue the shaft into the base, slot the middle onto the shaft, lock the middle to the base, plop a ball bearing into the gap between the shaft and middle. Then slot the lid onto the shaft and lock it all together with the cap making sure you dont accidently glue to lid to the middle. To unlock the box you need to flip it upside down, rotate the lid about 60 degrees, the ball will then fall into a slot made into the underside of the lid. which will allow you to pull back the middle, exposing the base cavity. This puzzle box I actually designed to be made on a Carvey CNC, But I made a few modifications so that it would work as a 3D printed model, although may not be ideal, depending on whether you like thick walls or not... In anycase, I've included a link to the fusion360 file so you can make modifications to it if you like. https://a360.co/3j5lacT If you would like the carvey project you can find that here: https://easel.inventables.com/projects/brWOaXnrnjKl8pz4bwFnaQ you'll probably need to make a few modifications depending on the thickness of wood you have available, but this should be a good starting point. I made the cap and the overhung section of the base out of bamboo. While the rest was made from birch. I used a 5mm dowel for the shaft.
