Important!

When using Customizer, a radius > 0 will cause the preview to time out, but if you press the Create Thing button, Customizer will create it!

• uses hex nuts or bearings as weights
• uses 1- 608 (22x7) bearing to spin
• uses 2-4X M8 or 5/16" hex nuts, 608 bearings or 3/8", 1/2" or 5/8" loose ball bearings for weights

Customize:

• edge roundness (radius)
• which weights: bearings or hex nuts
• the number of peripheral objects (yin-yang)
• The rotation angle of the peripheral objects: 2, use small, around 120; 4, use large, around 160-170

Note:

• The all bearing options require a large hand for a one-handed spin (Sorry, Donald)
