This was originally an STL file I grabbed from the MachiningCloud.com
My printer only has a print volume of 125x125x125mm so you'll probably want to scale this up.
I converted the STL to an IGS with FreeCAD and modified it in solidworks, I provided all the files here for you to remix
I also made a little adapter for it so it can be fixed to a fidget spinner and rotate, although it's pretty wobbly.

This was the first thing I designed and printed on my printer a couple of years ago, so I don't remember what settings I used to print. The filament is a gold colored Silk PLA
