Have you received filament with spool already damaged like these? 

=======================================================

For installing on a Kingroon filament spool, you will need:

1.) M3x14 screws - 4/6pcs [or longer if you don't have short one(max 25mm)]

2.) M3 nut - 4/6pcs

=======================================================

Not sure if just me being unlucky or what, about 3 out of 10 filaments(from every shipment/order) I got from Kingroon have different level of crack on the spool. It was not an issue when I was using Ebios Easdry which was hub loaded. 

But now I have upgraded to Ebios Polyphemus which uses roller system, cracked spool becomes an issue. I don't want to spend 15-20mins to wind the spools using something like this

So I have draw this rim saver to continue to use back the damaged spools
