Xyzprinting Da Vinci 1.0 Pro Spool Holder

You need to make your own bearing for spool.
I use ESUN filament and they use 52mm inner hole size spool.

If you use 52mm dia spool, you can use this. (Hole size is 8mm)

You need 2 bearings for rotation.

And If you need to change bearing size.
Please use this customizer.
