Yet Another Nerd Solution - Eryone Spool Holder

Disclaimer:
Use this thing at your own risk, it works for me, you are modifying the 3D printer. The author or the hosting site cannot be held responsible if anything goes wrong and messes up your print, machine or if your house catches fire. Use common sense and always wear proper protective gear when using power tools, grinders, drills, etc.

Remix for Eryone 3D printers (Thinker S/SE and ER20), may be suitable for other printers.
