Makerbot Replicator 2 and 2X Adjustable Feet

Are all of your work surfaces level? Sadly, mine aren't (old house syndrome). Does your Makerbot Replicator 2/2X balance on three sides? Is your manual stuffed under one side to keep it from rocking?

I made this adjustable foot by using some left over 8mm adjusters from an Ikea bookshelf. I've included a .stl file of a foot that will accept an 8mm bolt if you don't have any extra Ikea bookshelf parts laying around. Just take an 8mm x 40mm or longer bolt, heat the end up and press it into the foot.
