Simply an alternate Makergear M2 (revision E printer) Z-Axis knob. I printed mine and had to do a little sanding with some 60 grit then some 400 grit to get the metal collar to fit into it but it works great. I felt that it was okay to do some sanding because I know that the collar needed to fit snugly into the knob. I placed a small notch into the part so that the allen screw didn't hit the inner wall and it helped to orient the two pieces. Instead of having M2 on the top like this file has, I decided to place an Autobot emblem onto the top of mine that I found here: http://www.thingiverse.com/thing:1131435
I printed it on fast setting as the shape is pretty basic, nothing special.
Have fun!
