kossel spool holder

this is a remix a made based on BOrax Kossel compact Filament Spool Holder concept.
i found ball bearings at size of 19 mm OD 6 mm ID and 6 mm width so i made the parts to fit them.
i included the STEP files so you can make changes if you need to fit other bearings.
it is designed to connect with two M4X8 screws and washers and two M3X8 screws directly into the small holes to secure the bearings.
