Summary

Visit http://fidgetexpert.com/best-spinners/ for more of my projects.
UPDATE3:
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.

UPDATE 2:
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.

UPDATE:
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.

!READ BEFORE DOWNLOADING!
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.

FULLY WORKING VERSION OUT!

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?
