Printrbot Hinged Spool Holder

I got inspiration for this from another spool holder, but decided that it needed a hinge for easy loading and unloading of spools. I also sized it to utilize cheap electrical conduit as the solid rod ($3 for 10 ft. at a hardware store). It should fit any printer that uses the same 12mm smooth rods that the printrbot has.

WARNING!
1.This spool holder sits on the smooth rods, so it reduces your max build height. If you need the extra couple mm, just remove it.

1. When X carriage is raised up high, don't attempt to home the X axis. The spool holder will hit the extruder motor, and it won't reach the endstop switch. Just make sure not to hit "Home All" when the X carriage is very high.
