Description
Just to see if it can be done I created a spinner using as little material as possible.
According to Cura it uses 0.97m of filament and weighs just 2g with a 15% grid infill and only takes 20 min to print at 0.2mm & 75mm/s
As you might expect from a design such as this - the outer bearing don't hold up to much abuse before they pop out of place, but it still spins perfectly well.
Takes 3 standard skateboard bearings, 22mm OD, 8mm ID, 7mm thick.
