Hey! First of my own design on thingiverse...

Just a simple wire holder... I had an upload error so it needs to be rotated so the holder pins are facing up. Try to minimize overhangs, but DONT use supports unless you feel like drilling out the guide holes. It is designed to hold 6 spools of wire... The wire can be found on sparkfun: https://www.sparkfun.com/products/11367
