Ultimate Filler

I was looking for a simple but effective way to store my spools on a shelf, where they could be easily used directly from there. So, I started searching for the best filament roller.During my quest, I came across 'Filler,' but it didn't work for me because many of my spools have a really tiny diameter center hole. As a result, I scratched the idea of using it (Plus, Filler is not really useful when not mounted onto something).Undeterred, I continued looking and stumbled upon 'The Ultimate Spool Holder,' which seemed perfect! However, my excitement waned when I discovered that I would need a lot of bearings, which were quite expensive in the area where I am living.As a solution, I decided to design a way to incorporate the excellent plastic bearings and roller from Filler into 'The Ultimate Spool Holder,' and this was the result. So, if anyone wants to save on bearings, enjoy the modified design!
