Summary:
This is a fully customizable spinner fidget toy. It can use many things as weights from Ball Bearings and Quarters to Hex Nuts and Clay or even Magnets and concrete. You can use pretty much any center bearing you like by entering its dimensions. I have used the very common 608 as well as the smaller 625 bearings. I uploaded a few pictures to give you ideas. One of my favorite spinners uses plain old steel BB's! Make sure you select "Ball Bearing Retainer" for the Hole Type when using round objects. I strongly advise printing a Test Node(Choose Node Size Test from the Part dropdown.) to check the fit of the objects you choose. Most of the spinners I have printed are just loose enough to allow the ball bearings to rotate freely yet none of them have ever fallen out.
I am perfecting the design and your feedback is appreciated!
TIPS:
If you choose the "Well" Outer Hole Type you will need to also print the "Well Lids" from the Part menu. They have a small lip that locks into the Well rim to close the chamber.
Accent Inserts can also be printed using another color to make cool patterned spinners.
They make really cool Tops if you use a Node_Radius of at least 28 and 5 or more 8mm-14mm Ball Bearing for weights. Just put a longer 3mm or similar screw through the Finger Grips. I filed the tip to a point and was able to get a top to spin well over 4 minutes with a short blast of compressed air!
i have ordered the ball bearings from both Amazon and Ebay. They are commonly sold as Slingshot Ammo. You can use any round objects as long as they have consistent diameters. Marbles will work, but can vary in size a bit.
