Optical illusion desk spinner

Spiral Sphere Spinning Desk Toy This is my model of the spiral spinning sphere illusion toy Assembly Take the upper Spiral Part Inset Bearing Connect the Upper Spiral part to the Base. If the bearings are loose, you can add a spot of glue. Make sure not to glue to moving parts. Snip some 1.75mm Filament and put it in the hole on the spiral top part. You may need to trim or glue. Use the same colour filament as the upper spiral part. This will look less obvious that he sphere is attached. Insert the Sphere onto the Filament that is inserted into the Spiral top part. If it is too long, trim it. You may need to glue. If gluing, make sure to adjust the sphere so the sphere layer lines are horizontal.
