FFCP 2016 Filament holder

The Creator Pro filament holder are very limited to the Flashforge specific spools.
Several other filament holder already exist but for many versions the friction is rather high.
Various holders are using bearings but they are either complex or not flexible in use.
To eliminate this issue I designed a new simple version, the minimum spool hole diameter is 45mm, for smaller holes other bearings have to be used.

This holder consists only of 3 self built relative simple parts, 2 bearings and one screw.
**And it really works great, no tangling since days!**


The design was inspired by:
* The great and flexible low friction holder from [DrLex](https://www.thingiverse.com/DrLex "DrLex"): [1741096](https://www.thingiverse.com/thing:1741096)
It has many and partly complex parts.
* The easy to use and to build version from [Fireflynj](https://www.thingiverse.com/Fireflynj "Fireflynj"): [2138600](https://www.thingiverse.com/thing:2138600)
I used it for years but it has high frict
