Modular Wire Spool Holder – Stackable, Magnetic, and Sanity-Preserving

A clean, modular wire spool holder designed for people who are tired of loose spools attempting to escape their workspace.

This holder comes in five variants, supporting 1 to 5 spools, and is fully stackable so you can scale up without redesigning your entire bench. Each slot fits spools up to 60 mm wide and 77 mm in diameter, making it ideal for common electronics, automotive, and hobby wire spools.

• Stackable design with corner slots for 2×4 mm magnets (or use pegs instead if you want maximum rigidity and zero nonsense)
• Integrated wire feed slots for each spool so you can pull wire cleanly without unstacking anything
• Simple, sturdy geometry that prints cleanly and behaves itself
