Filament Holder Short

I took the excellent model of Hugo's and remixed to be 20mm shorter (for filament reels no wider than 65mm) and adaptable to bolt onto the Creality Ender 3 V2 Spool mast.

I also redesigned the lower section of the main part to be a truss, giving extra strength + the spool reel is a tube for the same reason. Uses standard 608 Bearings i.e Skateboard bearings
