Model Description:
This is a compilation of common ball bearings. These bearings are designed to be printed in place, meaning they don't require assembly. The tolerances are adjusted to minimize play between the inner and outer rings while allowing the rolling elements to move freely. To prevent jamming between the rolling elements, there are two different variants of rolling elements guided in different grooves within the inner and outer rings.
Printing Instructions:
Since the rolling elements, depending on the size of the bearing, have a relatively small contact area on the print bed, it's important to ensure that the print bed has been properly cleaned before printing to ensure proper adhesion and avoid print defects. A glue stick may help, but in my experience, it's not necessary on a PEI plate. After printing, some force may be required to get the rolling elements to move freely. To do this, rotate the inner and outer rings against each other and check if all the rolling elements can rotate freely. They work best after some extended use or if you rotate the bearings more intensively. If the bearing doesn't loosen, it's likely that the filament needs proper calibration. If it still doesn't work, please leave a comment, and I'll adjust the tolerances accordingly.
Note: You might notice small points on the surface of the inner and outer rings. This is because the seam was changed to random to ensure smoother bearing operation and prevent the rolling elements from getting blocked by the seams.
Dimensions:
A total of 8 models or variants of the ball bearing were originally uploaded, consisting of 6 standard sizes and 2 variants in special sizes. Additionally, more bearings may be added later upon request.

Note: If you require any specific dimensions, please feel free to leave a comment, and I will promptly add more models.

Print Plates:
The print plates are named according to the bearings, making them easy to select.
The print profile consists of a total of 11 print plates.
The first print plate is a compilation of all 8 ball bearings. It is configured to print the bearings one after another, not simultaneously.
Print plates 2-9 are each for the individual ball bearings, one per print plate.
Print plate 10 contains the special sizes on one plate in case someone wants to print the fidget toy. In this case, the ball bearings need to be pressed together after printing.
Starting from the 11th print plate, there are ball bearings that were added later upon request.
If you want to create your own collection, you can also download the STL file and design your own print plate.
Enjoy printing!
