Stackable Freestanding Filament Rack

I made this filament rack after seeing a similar rack built by uCHobby (Filament Rack Adapter https://www.thingiverse.com/thing:2294603). I was looking for a more vertical rack than any I found online. Unable to find a a rack that would stack vertically, I designed one using Autodesk 123D. By adjusting your conduit lengths, this will create a rack as tall or wide as needed to fit your available space.

This rack uses 3/4 EMT galvanized steel conduit (a bit overkill as other designs used 1/2"
