Print with the flat side down, as shown in the model.
This model works for Kobra 2, Neo, and Pro. I have updated the photos to include the proper way to install the holder. This way the spool does not come into contact with the printer in any way.
Install backwards with the spool behind the printer.
Uses 2 M4*8mm screws, holds 1KG spools perfectly well and saves a ton space compared to the one that comes stock (mine was also broken out of box and I didn't feel like wasting any more filament than necessary).
Please let me know if there are any issues, reviews and makes are always appreciated.
For better fit, you can also print “Spool Inserts” for your specific brand of Filament, or slightly grease to prevent squeaking with plastic spools. I am currently using the Overture Spool Insert by @BenOvation3D_1228145.
