Mendel Max frame top spool holder
by Wired1, published
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.
Print it out, I used PLA with 2 perimeters, two tops and bottoms and 40% fill.
You will also need two pieces of threaded rod to suit the size of the reel you are using plus another piece for the axle. I used 2 x nylock nuts - 1 each end of the axle - plus 4 x M8 nuts and 4 x 8mm washers for the uprights.
Follow the pictures, tighten enough to stop it moving but not enough to break it :)
Attach the two uprights to the top frame cross bars with 5mm machine screws and T-nuts same as you used to build your printer.
