I wanted one that was easy to print with a disk in the center which could potentially be embedded with a symbol.

This model is made to .3mm tolerance: any 3d printer should be able to be get tuned enough to print this. Plus, this gyro doesn't have a tiny ball in the center that people with fat fingers (like me) can't even interact with.
Use my design as a basis to embed your own symbol if you like! Here is the OnShape link.
Printing Instructions:
- Print flat with the widest part of the keychain loop against the bed, no supports needed.
- Infill may make the keychain lighter but feel less satisfying to tinker with. I printed with 3 walls and 20% gyro infill and that made the outer rings solid with only the inner disk having any hollowed parts.
- Tune your printer to .3 tolerance (preferably to .1). If using Cura as your slicer, you may find that tweaking flow percentages for walls and top/bottom/infill will help, and once you've done the best you can get the rest of the way there by tweaking Horizontal Expansion.
- Positive values in Horizontal expansion will make the print swell in X/Y directions. Holes will shrink.
- Negative values in Horizontal Expansion will make it's outer edges retract, and holes will widen in X/Y direction.
- PETG seems best because of it's glossy surface that slides well against itself, but PLA may do well if your outer wall surfaces are very smooth.
- The more you play with it the better it spins
- The better your printer is tuned, the less work you need to do to get it to spin well. There is a great calibration guide and set of tools on Teaching Tech.
- If you have any zits on the inside of one of the disks you can clean them up with a tiny piece of torn sandpaper. Stick it between the disks and use the inner disk to move the sandpaper around the inside of the outer disk.
- Hint: You can lightly sand and then heat polish by (very briefly!) exposing the scuffed area to heat/flame. Be careful! Follow all safety precautions and keep the exposure to milliseconds so you don't burn/melt anything!
Kanji Version:
- My Japanese knowledge is limited to 1 year in college, but I thought this symbol (情) felt like a great one to have on a fidget, especially for keeping calm or cheering me up.
