thecharacterg did a great rework of my Replicator foot, and I've only changed his work slightly here. I mainly published this to point out the use of the Sorbothane Isolators. I'll be the first to tell you that they are absurdly expensive for just a foot bumper. But the pads I used originally were highly compressed under the Replicator weight, and it actually looks like they are compressing more with age. Plus, the weight of my Replicator is increasing, with the XL mod, and new aluminum platform arms. The Sorbothane bumpers are perfectly sized for the weight of the Replicator+. When you get one of these in your hand, you'll see how different they are from a common foam pad or rubber bumper.The Sorbothane Isolators are available here: http://www.amazon.com/gp/product/B003IMJ3S2/ref=oh_details_o02_s02_i00Note that this is for a quantity eight, so there are enough there for two Replicators (or whatever else you might want to isolate). The .scad file and .stl have been changed to accommodate the 1.25" dia of the isolator. Pretty much just print, peel, and stick; then put the foot on your Replicator. I've noticed that the plywood thickness seems to vary a bit, so in case these don't grip the sides tight enough, I've added a couple of holes on the inside edge that could be used for some 3mm screws that should do the job.If you think you can bridge the inset on the foot, go ahead and try (it wouldn't show later anyway), but I printed with support.
