Universal Spool Roller

A spool holder that accommodates multiple sizes of spools is designed to require four 608 Ball Bearings to complete. Four M3 bolts with lengths of 25mm are needed; ensure they do not exceed the dimensions shown in the image. Four M3 hex nuts are also necessary. A new design for roller pins has been implemented, eliminating the need to pause the print process. This allows all pins to be printed simultaneously. The roller pins feature low clearance, making them difficult to remove once inserted. To assemble the spool holder, print two roller pins and slide them into the bearing from each side. Use a soft mallet to knock them into place; a single swing was sufficient for this purpose.
