Rotating Fidget Toy

A rotating fidget toy.

It's also kind of a tolerance test. You may need a very well-calibrated printer.

Tested on a Bambulab X1-Carbon

Instructions:

1. Print in PETG! PLA will be too brittle and will break.

2. Select the option to print infill first in your slicer to take out a ton of post-processing.

3. Print!

4. Clean up stringing with a lighter or heat gun.

5. Allign both parts perfectly up and down. Don't angle them!

6. Press both pieces together until they snap into place.

7. Attempt to rotate them against each other.

If they rotate:

8. Continue turning until it turns freely. If it doesn't, proceed to step 8 in the "don't-rotate section."
9. Enjoy.

If they don't rotate:

8. Pull the pieces back apart
9. On the Piece with the protruding ring, take some sandpaper or a razor blade and trim down the bottom of the nubs.
10. Repeat 7-10 until functional.
11. Enjoy.

If it breaks:

Reprint, but this time in PETG or ABS. (ABS not tested on my printers)
