The 3D printed bearing with airsoft BB's is certainly accurate enough for this application, but the big worry is that it will break during impact with another robot (or a wall). Unfortunately, commercial large bore slew bearings like this, that are very flat and with mounting holes, are generally non-stock items and very expensive. My other swerve drive design, https://www.thingiverse.com/thing:1135618, uses a custom machined split-race bearing. When I get a chance, I'll be posting a hybrid design that is still mostly 3D printed, but that uses the machined steel bearing instead.
