1010 Filament Guide W/688 Pulley

Wanted to take the spool weight off my printer (think pendulum), so I came up with this setup. Only tried it with one print, but it seems to hold up just fine.

The part mounted to the printer attaches without any screws onto a 1" square profile. I have 8020's 1010 profile on my printer.

The pulley bracket uses #8 flat head wood screws.

Spool holder I used was from here: http://www.thingiverse.com/thing:1002299
