Great 'proof of concept' 3D print... this amazes everyone not familiar to 3D printing!This needle roller bearing prints as one piece. It has 12 rollers and prints (on a Replicator 2) so the designed in support can be removed in next to no time to leave an easy to spin needle roller bearing.At the time of uploading I couldn't find anything similar on Thigiverse. The key to it working is the clearances within the design and the designed in support.TIP: Spray inside from each side with a small squirt of silicone spray to make it spin really well.Easy print... something to fascinate people with.
