TSUSH Support Block (Spool Holder)

I really liked the compact nature of the TSUSH - The Smaller Ultimate Spool Holder
by Doc_Cleaner (http://www.thingiverse.com/thing:2193891) but it just felt a bit to wobbly when in use, like it was gonna fall over any second.

So I created a simply little holder that was the right width for the spool of filament I was using at the time, which has a 58.5mm inner width (3D Solutech Filament). So far the little holder is working pretty great.
