Spin Top Creation & Manufacturing

Spin Tops
1

Hey guys, new here.

For a college project I am working on creating a 3d printed spin top. I’m basing the design off of the Strummol8 Giulia, but a bit wider.i am designing it in solidworks.

For anyone that has designed one, is there a “sweet spot” for center of mass compared to the tip, or is there a moment of inertia sweet spot? Currently I have most of the weight towards the outside, with the inside being a hollow cavity. The top does wobble a bit, which could be from off balance or something else. It also doesn’t spin very long, which could be due to the friction from the top being 3d printed, not sure. Will post photos when I get home.

Check out this site. The sweetle is an awesome 3D printed top. Also my sweetle has a bit of clay/putty on the inside to balance it out.

Thanks yoyojoe, I appreciate it. I will gladly check that out and do some more research on balancing. I remember reading a post here about balancing tops. I’ll read it again.

@TryCatchThrow Keith might be able to give you some help! I’ve bought a few 3d printed from him! Good luck with the project!
