Bearing - Needle Roller type one piece print (with minimal support to remove)

thingiverse

This is an incredible 3D print proof of concept! It leaves even the most experienced 3D printing enthusiasts amazed. The needle roller bearing prints seamlessly in one piece, featuring 12 precision-engineered rollers. Thanks to the well-designed support structure on our Replicator 2 printer, removing it takes only seconds to leave a smooth spinning mechanism. At the time of this upload, no similar models could be found on Thingiverse. It's crucial to maintain precise clearances within the design and carefully remove excess material in key areas. Pro Tip: Lightly coat the inner components with silicone spray from both sides to achieve exceptional smoothness. This impressive print is sure to wow observers due to its simplicity and high quality results. Instructions: Print on Replicator 2 using Raft settings with 4 shells at a 35% fill density. To prevent shrinking of clearances, refrain from scaling down the model. The support structure will collapse into one cohesive unit, allowing easy removal. Once printing is complete, carefully disassemble the excess material supporting the rollers, and it should come loose instantly as they're connected by a single supporting ring.
