Metal Plus Spool Holder

cults3d

I had an idea for a spool holder that sits on top of my Printrbot Metal Plus. The printer design is such that you can just set a spool up there, and it pretty much works, but I was worried it might fall over or something. I took the 80mm gap at the top, and used pieces from http://www.thingiverse.com/thing:178862 to create a spool holder that rests on top of my printer and fits into the gap, but uses the bearings instead of just resting on the bare metal. I used a couple 1/4 20 lag bolts to act as spacers, and hold it together. Not bad for a first draft of an idea. This thing was made with Tinkercad.
