spinning gears for test print

thingiverse

You can experiment with the Slicer settings to see how they affect your prints. Check options like Stringing, Retraction, and Solidness to get a feel for what works best for you. Keep in mind that one common problem people face is called "elephant foot." It's usually caused by the first layer expanding slightly and the gear hole becoming narrower. This can prevent gears from spinning smoothly. To fix this issue, try inserting each gear into a pillar upside down, pushing it deeply, turning it hard, removing it, then inserting it back in the normal direction.
