spool holder for printrbot simple metal with aluminum handle

This is a spool holder for the printrbot simple metal. It slides onto the aluminum handle that comes with the printer. All you need is an 8mm rod to go through the hole to hold the spools. Also pay attention to how close the spool is to the y axis when the z axis is all the way up because it will jam. I used a spacer to stop this from happening. It is also important to keep the weight even on each side or it may tip over.

print with 100% infill for strength
