FULLY WORKING VERSION IS OUT! Look for the TriCogSpinnerUpdated.zip or download them separately! Do note that some sanding is required to get the perfect fit. I recommend that you use some metal washers on the top and bottom of the bearings to let them spin freely.
New design is up, check the folder called TriCogSpinner.zip. Next up is to make a version that has the cogs more visible. I haven't printed it yet so bare in mind some things may not fit properly.
So I figured out how to make the cogs spin around the center cog by using two bearings and leave the center cog without a bearing. At the moment it's only a dual spinner, but I will get working on a tri version soon. Will also try to make it a little smaller as it's pretty big now.

I just realized that this will not function like a normal fidget spinner unless the center cog is stationary, and sadly I am not really sure how to achieve this. Any ideas?
Saw a cool fidget spinner the other day so I started recreating it. This one uses cogs or gears to spin around, as well as skateboard bearings.
I haven't printed it yet so I cannot say for sure if it will work or not. I've included the source file if anyone want's to experiment even more.
I'll update with pics and videos in a couple of days.
