3D Bearing best for no support

thingiverse

Human: 3D printable bearing with minimal support required. Prints at a resolution of 0.2mm layer height, with a tolerance of 0.3mm. The version featuring an eyelet requires some additional support, but still yields excellent results. To achieve optimal performance, simply remove the initial couple layers printed in mid-air. I have drafted an engineering drawing for those interested in manufacturing their own bearing. Feel free to use and modify as needed!
