About this 3D model
I had a problem I liked: 100% printable filament spool by abliss: http://www.thingiverse.com/thing:5766 But I thought that the hub was a bit over designed (3+ hour print). But then I found: Makerbottable Simple spool system by randyy: http://www.thingiverse.com/thing:4337 Which provided two great hubs. So I created a way to use the hub of the second item with the arms of the first. Both designs are great, and I want to thank both authors for doing all the real work. I just bade some "glue" to combine the two.
