Filament Spool Holder

Spool holder for standard 1KG filament rolls. I used these as part of a project to build my own sealed filament storage.

When printing, I tacked a couple of support enforcers around the top lip of the holder piece in the middle just to give it a bit of support (I'm new to modelling and didn't think ahead to try and design the holder so it didn't need supports, sorry!). The frame itself doesn't need supports.
