Filament Roller holder shorter - Remix

The rolling spooler support works very well, but I need to save space in the enclosure. So I've optimised the length for my needs and shortened the model by 2cm Original: 140mm Shorter: 120mm The width of the spooler should ideally be under 70mm and a maximum of 74mm. For further information, please refer to Dirk's original model (or HugoG from which it is derived).
