Magnetic, Interchangeable Spinner

Watch the Demo Build Here:

Yes, the world is burned out on Spinners, they had their day - and it's gone. That said, this one is truly a clever concept. Wish I could say it was my idea, but it was my daughters (age 13), I just made the pieces work.

What's different about this one:

• The addictive SNAP of the magnets as the two halves click together
• The mini spinner embedded inside can be a standalone finger spinner
• The cool pushbutton action when you press on the bearing if the spinner is laying flat. Useless feature, but fun to press the button
• It has three unique components, you need all three to make one spinner.  The two halves are mirror opposites.
• Prints are simple and fast
• Try the Wobble spinner here:  https://pinshape.com/items/105...

This is a fun 3D printing project because its something usable, tradeable, highly interchangeable, and fits into a pocket or  backpack.  It's not just a figurine, it has functionality. 

Printing Tips for PLA:

• No supports
• 20-30% infill for upper and lower halves
• 40-50% infill for mini spinner inside (the rolling bearing presses into it, it needs to be a bit stronger)
• 0.15mm layer height on everything
• I recommend using glue on the heatbed, very thin, uniform layer 

Other components you'll need:

• Eight .125" diameter by 0.125" long magnets  (my favorite place for ordering magnets is www.KJMagnetics.com)
• Four, 1/2" diameter ball bearings (these don't need to be precision)
• One, rolling bearing (608ZZ trade size) This is a just a common skateboard bearing.  Measure the outer diameter and make sure it's .866",  x .276" thick  (Just take one out of your other old spinners, it may be an exact fit)
