Standalone Rack for the UM2 Spool Holder.If you want a little more flexibility in positioning your filament spool you can print (and try) this spool rack. Edit 16.08.2016: a more sturdy version 2 can be found here: https://www.youmagine.com/designs/ultimaker2-spool-rack-version-2 It is designed for a use together with the "Low friction UM2 spoolholder" by IRobertI (https://www.youmagine.com/designs/low-friction-um2-spoolholder), but the stock spool holder fits also well.Just print the backplate and two feets and glue them together (if you like).
