Filament Spool holder for 30x30mm Aluminium extrusion

Spool holder to suit the Verbatim spools but also the wider 3rd party spool. For the narrower spools 2 spacers have been supplied. The spidle end has a left hand thread and nut to keep the spindles from falling off. Since the spool unwinds in an anticlockwise direction the LH thread will not come loose. Mounting to the extrusion is by 2 x M6 T-bolts. See my blog http://d3delta3d.blogspot.com.au/ for the delta printer build progress
