Geeetech Prusa I3 Pro B Filament Holder w/ Adapter

This is a Filament Holder for the Geeetech Prusa I3 Pro B (original design by [TheRealNapalm](http://www.thingiverse.com/thing:1860754)) that supports a 20mm pvc pipe as many 3d printer clones come with.

Also included a stack-able adapter in case your spool interferes with the lcd panel. Print as many of them as you like and make the holder as tall as you like.
