Adjustable Filament Holder (which may also be used as pulleys)
thingiverse
The original filament holder for my UP! Plus printer wasn't versatile enough due to varying spool sizes from multiple suppliers. Searching Thingiverse, I found only two adjustable options, so decided to create my own customizable design that could be printed without assembly. I replaced the filament guide with one from Thingiverse (http://www.thingiverse.com/thing:31961). To print, use the provided STL file twice, maintaining its original form. Carefully remove support structure to release wheels and enhance stability by adding two BBQ skewers as depicted in photos. Adjust width according to spool size preferences.
