This is a simple foot for the excellent MendelMax RepRap ( http://www.thingiverse.com/thing:12645 ). I didn't like having the frame resting directly on a surface, especially when using black anodized aluminum. This helps prevent scratches. I didn't find any type of level adjustment was necessary.Simply print and use with 2 T-nuts and 2 M5 10mm screws. You might have to clean the holes a bit, since the indents for the screw heads cause an overhang. It would probably be a good idea to add some support that could be cut out afterwards.
