Feet (though I haven't bothered to install them as I have no vibration issues):

Now, I have switched over the ABS (the glow in the dark green above) and started using Cura for everything. I don't like ABS nearly as much as the PLA. PLA just worked and didn't curl, etc. With the ABS, it sticks well to the blue painters tape, but on large prints (e.g. the Tie Fighter for the boys), the edges would warp and pull the painters tape off the glass.
