I've designed a custom spool holder with a few extra components to allow you to store filament inside of the Da Vinci enclosure. This keeps everything nice, clean, and organized. Although the spool holder looks typical, I designed it to "lock" into the slots on either side of the Da Vinci. This keeps the spool from moving.

UPDATE: Added new versions of corner hoop and distributor. These new models "snap" into place so that very little glue is required (much better reliability)

ANOTHER UPDATE: The distributor part still failed after 10 hours of printing, so I have uploaded a Version3. Print this along with Distributor_nut. The nut will twist onto the bottom of the distributor to lock it into place.

AND ANOTHER UPDATE: Check out the various remixes before printing. The community has come up with clever solutions to a few of the problems with the design.
