Hi Tech? NO!!! Low Tech - but, SOLID Design - that simply WORKS!
I used to hang my spools off a shelf - above my printer - using a Coat Hanger! JetGuy used to tell a story of when he did something Similar - but, DAMN IT - he didn't have a PIC to prove it!!!
Ask me what happened...
Even though - you do Not know of him...
I may have to share some JEtguy videos...
