I needed a fast and reliable spool holder with easy assembling system so I came out with this design. You will need two 608 bearings in order to assemble it.
A 40mm PVC tube can be used instead of its homolog printed model.
This tube should be glued to both end caps with hot glue or any other type of glue.
608 bearings can be inserted on the axles without glue and can be locked with 1.75 filament pins.
