Two-Part Threaded Spool – 50×40 mm | Support-Free | Perfect for Wire, Filament & Storage

This 3D model is a compact two-piece spool designed for organizing wire, small filament samples, or any flexible material that needs clean and controlled winding.

The spool measures 50 mm in diameter and 40 mm in height, offering a practical balance between capacity and portability.
It prints in two separate halves, each featuring precisely modeled male and female threads that allow the parts to screw together smoothly and securely.

A key advantage of this design: it requires no supports, ensuring clean prints, faster print times, and optimal filament usage. The geometry is optimized so every feature prints neatly on standard FDM printers without extra material waste.

This spool is functional, efficient, and satisfying to use—perfect for makers who appreciate well-engineered, support-free designs.
