MakerBot Eraser Feet

Hello everyone,

this is the first part I ever made on blender, actually I only modified it, but still hard to do for a noob on blender, like myself.

I´ve seen tbuser great design:

but I was not able to find the right size O-Rings in Brazil, so I decided to make a new version that would fit things that I had laying around the house.

I used regular school eraser for the feet... they are soft enough to not let the vibration transfer to the table
