I was scrolling through the comments section when I saw a user post that the spring fell out of the bottom, and when I examined the model's geometry, I found the bottom was only a layer thick. So I had to fix it, just a simple flat cylinder at the bottom. You can use any material to print, though more flexible materials (like PETG) instead of stiff materials are recommended. Make sure your printer has good cooling. Any well-calibrated printer can do this, irrespective of brand or printer type.

Settings:

• 0.2 mm layer height

• Print speed between 50 and 70 mm/s for good cooling on the spring

• Can be printed with no infill, although if you are, make sure the spring is solid using at least 3 wall loops/perimeters.

Happy fidgeting!
