Universal spool holder for 625 zz size bearings

There are a lot of filament spool holders out there but i couldn't, with a quick search atleast, find one that would fit my needs, i only had 625zz size bearings and i didn't want to waste so much plastic for such a trivial part, so i decided to design the holder by myself.
This design does not require a lot of plastic (only 5 meters of 1.75mm for the two) and yet it works very well.
