Filament Spool Holder

When I bought this printer it didn't come with a filament holder, and while it has served me well for a lot of printing, it seems silly having some chopped up scrap wood holding the filament. According to some quick measurements, this ought to fit the bill and allow for some smooth enough spinning, until I decide to put some bearings into it. Noticed some other useful parts on the Fusion3 Group here, so thought I would throw this up in case it can be useful to someone else.
