Slew bearing with crossed cylinder rollers

thingiverse

This is a durable and impressively effective bearing. Its design empowers you to create your own functional bearing, despite the relatively low precision of a 3D printer. If excessive or inadequate play occurs, adjust the tolerance for rolling surfaces and reprint the rollers accordingly. It comes in separate parts, necessitating straightforward assembly. In contrast, all print-in-place bearings I've tried exhibit too much play to be truly useful. They inherently require a larger play allowance to prevent the parts from sticking together during printing. Please utilize the customizer to generate STL files tailored to your specific needs. I extend my gratitude to TheGoofy and his Slew Bearing (see remix note) for their initial design. I rebuilt it in OpenSCAD and integrated the cage/spacer as a single part.
