Horizontal Spool Holder

Hey,
This is a basic horizontal spool holder. it works very good.
It consists of four print parts.
You also need:

25 Steel balls (Ø 9.5mm) >you can also use 28, but in my oppinion 25 works better<
one screw M6x30
two washers 6mm
one self-locking nut M6
six anti-slip pads

Do not over-tighten it (M6 screw). Leave a 0,5mm - 1mm gap.
You should also glue together Part2 and Part3.
The steel balls are slingshot ammo.
Supports needed only at Part1.
