Filament Holder Spool

This project was inspired by the work of mjoaris . It pleased me immensely, both the aesthetic and functional concept. However, the hole in my reels is very small, only 45mm in diameter. For this reason I had to redesign the components to fit my needs.
From the original I just kept the roller.

It consists of 3 (three) components:

Holder (FilamentHolder_135x40.stl);
Nut (Nut_38x15.stl);
Roller (FilamentRoller_80x20.stl).


Also we need 2 (two) bearings (608RS or 608ZZ): 8x22x7mm.

Benefits:

Compatibility with various types of reels;
Better bearing fit;
Thanks to the square base, it can be applied to both vertical and horizontal supports.
