This spinner uses a standard 608 skateboard bearing in the middle hole, and 14mm steel ball bearings as weights. The ball bearings can be pressed in by hand.

Print two of the caps to place inside the center - if you find they're too tight scale them down a few percent and print again, and if they're too loose just glue them. You can also make custom caps here.

I found the large 3-ball spinner was too big for kids' hands, so I've included a smaller 2-ball version for kids.

I recommend these bearings.

awesome, those balls are the same size as the ones that are in my old magnetics set. One question, i am thinking about designing my own steel ball spinner and was wondering if it is alright to have the hole straight or do i need to do what you've done and make a slight rim mid way through the hole for the balls to sit in?

That ridge is necessary to hold the ball-bearings in place. If the edge is straight the ball will either go straight through, or get stuck before it reaches the half-way point.

awesome thanks :) is there any specific size or design for the ridge that works best?

I experimented with many different sizes until I finally settled on this version, which holds the 14mm balls tightly, but they can be pressed in by hand.

Hi there, thanks for the design! Can you upload the design files so it can be altered for different size balls?

I made it with polygons in 3DS Max, so the design file is exactly the same as the STL file.

what size balls do you use

14mm diameter.
