Flashforge Finder Spool Holder (Piggyback style)

I wanted a holder that didn't require me to leave the cartridge door ajar, so I built this. It works well. It is very strong with 30% infill.

I designed with a square attachment which will allow me four rotations as the mandrel starts to wear. You can easily adjust the mandrel diameter for different spool IDs.

I recently ran out of red PLA, that would make it look more OEM!

EDIT: I Added the filament guide to the files and to the 123D Design files!

Take a look at the new photos..
