This is a fun fidget that fits nicely in your hand (or pocket) - especially when visiting the Happiest Place on Earth:)

3D PRINTING SETTINGS: Layer Height 0.2mm PLA works great Infill 15% No supports needed Smooth print plate recommended

Dimensions: 2 1/2 in x 2 1/4in x 7/8in

You could scale up on this but I would caution about scaling down too much because that will thin the walls and tighten the spaces between the layers resulting in a less satisfying fidget. Have fun printing & fidgeting!
