Robo3d Filament spool holder

Here's a remix of Noudje's spool holder. I adjusted it to use M5 screws and roller bearings which are 14x5x5. Linked below are the bearing I purchased for this project. The M5 screws I acquired from Ace Hardware, and as such, any major store like that should carry some.

Each wheel houses two bearings on either side, so you'll need 8 bearings in total.
