Poor Man's Spool Holder

I needed a quick and easy spool holder for my CR-10 after moving the control box under the printer itself with some 3D printed legs (there are models on thingiverse that look much better than the one I'm using, like this one! https://www.thingiverse.com/thing:2332197). Instead of printing a frame and spindle and the like, and since I didn't have any ball bearings, I modeled a base that the spool holder that came with the CR-10 could be attached to.

I used two M3 bolts and nuts, but I bet other sizes would work well too. Just make sure to use actual nuts instead of relying on threading into the plastic itself as the spool holder needs to hold up, well, usually a good kilo. Or bad kilo. Your choice of filament here.
