Tired of chasing runaway bobbins across your sewing table like a fabric-wrangling cowboy? Meet Bobbin Fortress — a sleek, practical, and slightly overengineered 3D-printed organizer that keeps your bobbins perfectly lined up and ready for action.

This design comes in two versions:

• 🧲 Magnetic model: uses 4 magnets (10 mm x 4 mm) to cling securely to your sewing machine — no drilling, no commitment.
• 🔩 Screw-mount model: for a permanent setup — because some sewists like things locked down.

Holds up to 20 bobbins, ensuring your threads stay neat, visible, and within reach. Designed for makers who value both functionality and flair, whether you're sewing for passion, profit, or pure thread-based chaos.

Print it. Load it. Never lose a bobbin again.
