Looks awsome... now does it work well? Ehh its a spool but looks like you would need a lot of pastic to make thewalls even if you use very little infill

FWIW I found a cheap alternative at http://store.osprintingllc.com/ProductDetails.asp?ProductCode=SP-2

The spool and spooler looks like something that can be easily modified to adapt directly to the spool motor. More so than the existing solution.
