Filament Spool Holder for UP Pro and Mini

HI all

I have created a filament spool holder for the UP 3D Printers. This will allow you to use a wide variety of filament spools with you UP 3D printer.
I have printed off 5 of these already and they really work well.
They also stop the spool from falling off the printer, which happens with the factory supplied holder whilst printing.
