D2.4 cm ball bearing. Engineered for seamless in-place printing, it features 15 tiny balls.
Feel free to print and evaluate its potential - your insights will be invaluable in refining this concept
Please note that initial rotation may be restricted due to the spheres making contact with both the upper and lower layers during the printing. To activate the bearing, exert rotational force on the outer ring. This can be easily achieved by mounting the bearing onto a pen or a similar object, thereby fixing the inner race, and applying moderate force to the outer race to sever the initial contacts.
Applying a small amount of lubricant (example: silicone grease) will improve performance.
