This is my favorite adaptation of the side mounted spool holder that utilizes the original metal spool holder. It combines two designs (side spool holder bracket and 608 Bearing Roller) into one very rigid and sturdy side mount solution.
I printed the Side Spool Holder Bracket with 100% infill for strength. I followed a user's comment and added some felt lining on the interior so that the bracket would not scratch the printer over time. I was also able to re-use the existing screws to attach the bracket to the printer.
