Designed by Thingiverse user 2ROBOTGUY, the Tri Fidget Spinner Toy has gained lots of likes, makes, and remixes on the 3D model platform. To start things off, here is a classic 3D printed fidget spinner, one that resembles the sort that are mass produced and sold at drug stores. And while you could go into your local shop (really, pretty much everywhere is selling these things) to buy a fidget spinner to fulfil your spinning needs, why not take the DIY approach and 3D print one of these awesome and creative fidget spinners, brought to you by the maker community.īest Fidget Spinner Design/Toy to 3D print #1: Classic Tri Fidget Spinner If you don’t already have one, we highly suggest getting your fingers on one.
Lastly, I trimmed the edges and lines I didn't need and extruded the sketch by the thickness of the actual body of the spinner.Fidget spinners have been all the rage in 2017, entertaining and relieving stress for both children and adults alike. Then, I drew arcs between the larger circles around the weight spaces and the larger circle around the bearing space. In order to model the round shape of the spinner, I drew circles a little larger than the weight spaces centered in the circles for the weight spaces and also drew a circle a little larger than the bearing space centered in the circle for the bearing space. I also drew a circle dimensioned to the size of the outer diameter of the bearing and centered it at (0, 0) to make the space for the bearing. I then moved these circles and positioned them so that one circle was centered in rectangle width wise and the edge was tangent to the edge of the rectangle for each wing. To make the spaces for the weights, I drew three circles and dimensioned them so that they matched the inner diameter of the spaces I measured on the actual body. This rough shape will act as an outline so that I can be sure that the body has the correct dimensions. I removed those lines and the intersecting ends of rectangles, leaving me with the rough shape of a three-wing spinner. Next, I drew 1" wide rectangles intersecting at the origin using the lines as the center. I also made these lines at a 120 degree angle from each other and dimensioned it that way so that it would be symmetrical. I drew these lines from the origin on the sketch plane so that the center of the spinner would be (0, 0). I started by drawing three lines the length from the center of the spinner to the edge of the wing. The Body was the only tricky piece to model, and it really wasn't that bad.

I just eyeballed these circles since the software snapped to existing ones and the actual thickness of the rings isn't a critical dimension for the model. To create the aesthetic parts, I made a sketch plane on the ring and drew four circles, two of them matched the edges of the ring, one was a little smaller than the outer diameter, and the last one was a little larger than the inner diameter. I did this so that I could add the aesthetics created by the rings and the cover, but if you aren't modeling those parts, just extrude the sketch by the thickness of the bearing.j Then I extruded the sketch 0.05" less than the thickness of the actual bearing.
I started by drawing two circles on a sketch plane and dimensioned them so that one circle was the same as the outer diameter of the outer ring and the other was the same as the inner diameter of the inner ring. But I like to model the aesthetics, so I did that too, but I didn't bother to get exact dimensions of those parts. For the bearing, the only dimensions that really matter are the outer diameter of the outer ring and the inner diameter of the inner ring.
