Most people encounter problems and create solutions.
I'm not like most people. In this project, the order has been reversed.
The design of the universal caster ensures that its wheels are always aligned with the direction of travel. However, the way this reverse caster rotates makes the wheelsNeverMoving in the right direction.
Its innovative design cleverly reimagines the standard function of caster wheels, enabling them to perform the opposite task. As a one-piece printed wheel, it actually rotates quite well. After applying a layer of lubricant, its rotation performance will be even better than you need, as it won't rotate at all when mounted to anything.
For the one in the picture, I added a layer of tape "tires" to provide better grip and make it more stubborn when it goes in the wrong direction.
If you want to enlarge it to play a prank and replace someone else's office chair casters, you may need to adjust the contour compensation, because the tolerance will be looser at this size
