Roller bearing with flange

thingiverse

This is a print-in-place roller bearing with a flange if you would like to screw it to a table or fixture. It takes a little work to remove the internal supports and some spinning to smooth out the bearings, but it works well in both tension and compression. This print is designed to only need supports from the print bed to the bottom of the rollers to minimize filament usage. You can glue a plate to the top if you would like a solid surface.
