Ball Bearing Filament Holder (thin)

This filament spool holder. It needs four 608Z (8x22x7 mm) bearings.
It is just a combination of parts from an original holder (https://www.thingiverse.com/thing:2221639) and it remix (https://www.thingiverse.com/thing:2267430).
As result it is more compact than the first one but form my point of view more stable than the compact version.
