About this 3D model
Pair or brackets to hold a filament reel above your Mendel Max printer. Brackets use a length of 8mm or 5/16" threaded rod so can be adjusted for different size reels. You will also need to make centres for your spools and maybe spacers as well. For the reels shown here I am using these centres http://www.thingiverse.com/thing:30366 and spacers.
