This is a remix of the swivel fidget toy by @KitCrafters. I added a couple layers above the magnets to encapsulate them. I used 6x3mm magnets so 6x2 should also fit. I inserted pauses at the layers necessary to add the magnets (before layer 22 for the two magnets in the swivel and before layer 26 for the three magnets in the base). I found it to be a snug fit but it worked, if it's too tight Kit Crafters has some good info about X-Y hole compensation on their page for the original model.
