Yes, the world is burned out on Spinners, they had their day - and it's gone. That said, full disclosure here: This spinner concept is my daughters idea (age 13 at the time) - I just polished the mechanics and fit.
What's different about it:
It has three unique components, you need all three to make one spinner. The two halves are mirror opposites.The addictive SNAP of the magnets as the two halves click togetherThe mini spinner embedded inside can be a standalone finger spinnerThe cool pushbutton action when you press on the bearing if the spinner is laying flat. (Useless feature, but fun to press the button)
*Prints are simple and fast
This is a fun 3D printing project because its something functional, tradeable, highly interchangeable, and fits into a pocket or backpack.
Printing in PLA:
No supports20-30% infill for upper and lower halves40-50% 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, a 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, these are about 16 cents each)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 of the rolling bearing and make sure it's .866", x .276" thick (Just take one out of your other old spinners)
Cheers, Mark
