Summary

This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/8uq69ZPA4ve

Based on the great design by Printrbot:

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.
