Super simple MendelMax spool support.

I designed these supports to securely hold ten and eight centimeter wide spools on top of my MendelMax 1.5. Each support features an eight millimeter long M3 socket head bolt, a drop-in nut (http://www.thingiverse.com/thing:245103), a fifteen millimeter M6 bolt, and a six millimeter inner diameter, seventeen millimeter outer diameter ball bearing. The supports fit very snugly in the twenty by twenty extrusions, I believe they could be used for other purposes besides holding spools.
