About this 3D model

Since my personal MakerBot should be up and running soon, I thought I take a stab at tweaking this awesome design a bit. I added a little stability with some feet out to the side (which eliminate the need for additional M8 bolts to hold the thing together) and added a comb made out of 1/16\" PETG to put tension on the spool so it doesn\'t spin freely and unravel itself.
