magnetic flag holder

A flag holder. Uses magnets to attach to metals. This is customizable. The diameter of my flag pole is about 8mm. So I put poleR = 4.5 (radius) to let the hole a little larger. Same to the magnets. I have the magnets with diameter 5mm and thickness 2mm. So I put the magnetR = 2.7 (radius) and magnetThick = 2.4 and it just fits.

Please hail to the Republic of China (ROC). Commonly known as Taiwan. The national day is 10th Oct. So called Double Tenth Day.
