The World's Largest 3D Printed Fidget Spinner

Back in March, the Boca Bearing Company set out to create (what was) the world's largest 3D printed fidget spinner using a Type A, Series 1 printer.

In order to achieve this, a scaling factor of 3.41 was used on the Cog Triple Spinner and Fidget Tri Spinner from Thingiverse. This enlarged the diameter of each hole from 22 mm to 75 mm and made the overall size of the spinner just shy of the area of the print bed.

The print time for these spinners was between 17 and 19 hours with 15% infill. The chrome steel bearing used is a degreased MR63009-2RS (75mm OD x 45mm ID x 23mm Width) which can be purchased here.
