A Better Filament Spool - Reel Holder for Makerbot ToM!

A nice easy modular spool holder that allows you to hold from 1 to 4 spools on top of your Thing-o-Matic! I have tried a few holders out there, and I was never fully happy with any of them so I finally broke down and drew one of my own.

Fully printable on ToM.

My favorite spool holder to date was the YAFSH by mikefrisina here http://www.thingiverse.com/thing:12974
But I didn't like how high it stood and it was a bit difficult to change reels out. So I took his dove tail design and made it into a hook style holder.

I also made this with a snap lip so it actually locks onto the top. There are also 2 holes that line up with the 2 M4 screws on top your Tom. You can mount the holder permanently with longer M4 screws or drill them out for clearance and leave the holder removeable.
