Spool Holder Top or Side

This is a free spinning spool holder with 6mm BB´s used as bearing.
This spool holder is meant to be mounted above the printer, either top-down or sideways.
I ended up putting a lot of grease into the bearing rail to make it scilent.
Additional items used:
- BB´s 6mm (a lot)
- M8 screw 800mm cup head 1x
- M8 nut + washers
- M3 screws 6x (can be replaced by small wood screws)
- grease
