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.

what caps are you using? due to the center cog you cant use the normal type that just fit in the bearing. so just a flat one and some glue? thanks in advance

Very nice!
is there any reason why sides have to be that thick?

Thanks! It's because there's a bearing inside. I could probably use a smaller bearing to get the thickness down a bit.


i think if you take your tri star spinner design and fit the cogs in there it may work

I kind of like it with all the gears turning.

I printed this out just to give it a try today. The male and female parts do not fit into each other. They are the same size. Just thought I would let you know.

Are you sure? I guess I should increase the tolerances a little bit more, I made it late at night so didn't really look it over too much.

Also 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?

connect it to the base?
