Spool holder for 6mm (1/4") thick frames.

This is a spool holder I came up with to hold on to 6mm (1/4") thick frames. I just needed a stand in spool holder while finishing the modifications on my 12 cubed printer. It works so well I thought I would share it with you, It has screw holes to clamp with and uses 8mm rod for the spool to spin on.
