Akimbo Spool cradle
by raldrich, published
A Spool cradle for Mendel style printers, and Ultimachine filament spools.
A companion piece for Akimbo - http://www.thingiverse.com/thing:28431
After having my spool roller bind up one too many times, I decided it was time to make a spool cradle that didn't bear against the outer edge of the spool.
This spool cradle is designed for use with Ultimachine spools - some adjustment will be needed for spools with different widths, or with a different size of center hole.
