11mm Steel Ball Sling Shot Ammo 15 oz

These precision steel balls are serving my purpose very well. I designed and 3D printed a "Marble Machine" that uses them as the rolling objects. I chose these because 1/2 inch diameter balls were too large for the mechanism as printed. The high level of precision of these balls is not necessary for my machine but they are a pleasure to use. I recommend these precision 11 mm ball bearings.

Just as advertised at a god price.
