My newest spool bearing for 2020-based printers. Uses one M5x10 screw & T-nut & 19 6mm balls (Airsoft pellets).
ASSEMBLY----------------
Taking care to align the hooks on the smaller half with the holes in the larger half, lower the large bearing half over the hub & snap it in place.
If disassembly is desired, insert a toothpick or similar object into the holes in the ends to release the hooks.
