Bill of Materials

This is the list of the ingredients that are necessary to build the Hackspace Prusa.

The original design uses a couple of smooth rods for the Y-axis, but we've used some angle-iron, and a couple of desk-drawer slides. It's a womble-ish solution... :))

If you want to provide the parts that we don't have yet, add your name to the volunteer section for the part, and go for it. There are links to the order pages for a couple of supplier's websites, but if you find one that we haven't looked at yet, then add them in.

If a part doesn't have a name attached, then it's one that we still need...
