This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/8uq69ZPA4ve  Based on the great design by Printrbot:  https://www.youmagine.com/designs/printrbot-simple-filament-spool-holder-no-aluminum-handle  I added some tool holders for my snips and spatula.  I also shortened the spool arm so that it could be printed with a Printrbot Simple Metal with the newly added tool holders.
