Spool holder, Toolless, Customizable fit, Securable

I made this remix as i really liked the way MartinMajewski did with his take on a spool holder with zero extra materials needed, beside the bearings,
But i wanted a spool holder that was not attached to the printer, so i decided to remix his creation with bmichels spool holder, to a customizable holder you can place on your table or were ever you want

Need 4 x 608 Bearings
