After upgrading to an direct drive system I just rotated the spool holder from sideways to frontways it was secured with one screw I didn't like that so I made this little adapter.
You might need a bit longer screws depending on the printer you use
This mod should be compatible with any printer that has an aluminum extrusion and the filament spool holder can be mounted on top and fead directly into the extruder
You can also use it on printer that has Dual Z there should be enough clearance between the belt and the adapter
