Z18 filament spool adapter

WE HAVE MOVED TO PRINTABLES:
https://www.printables.com/model/313088-z18-filament-spool-adapter

one of our students Nachum T. wanted an adapter to accommodate 3rd party brand filament for our Z18. other adapters typically fit to the top or back of the Z18 requiring removal of the chamber top (letting heat escape) or which take up space on the side of the machine (our lab is tight, and we don't have this room) - so an adapter was designed to fit to the tray -- yes this means leaving the tray door open during printing, so be it!

NOTE THIS IS FOR EDUCATIONAL PURPOSES ONLY as using 3rd party filament may void your warranty!!

we quickly printed the adapter parts on our Z18 to test this idea - and it successfully holds a spool of filament in the tray.

NOTE: a month ago our student had never 3D-printed anything, and now they're designing and printing adapter parts to make components inter-operable. Great!
