Fidget Spinner: The Flow

This is my first fidget spinner design. I wanted to create something simple, but cool. This is a simple design. Three arched supports, with three short, straight supports that intersect the arched supports. The picture features three different sizes:

The red design is 90mm in length, holds a 22mm bearing in the center, and two 10mm marbles, or ball bearings, in the end holes.

The purple design is 92m in length, holds a 22mm bearing in the center, and holds 15mm marbles, or ball bearings
