FREE 200mm Screw-Together Filament Spool Adapter – Digital 3D Print File

FREE DIGITAL DOWNLOAD – NO PHYSICAL PRODUCT WILL BE SENT

A simple, practical two-part reusable filament spool / spool adapter designed for FDM 3D printing.

The spool consists of just two screw-together parts, keeping assembly simple with no loose screws, pins or extra hardware required.

Perfect for filament refills, respooling projects or anyone who needs a reusable 200mm spool.

🧵 Designed For

This adaptor was designed around my 0.5 kg filament spools measuring approximately:

170 mm outer diameter × 49.33 mm wide × 52 mm centre hole

The complete original 0.5 kg spool sits inside the two-piece 200 mm adaptor, allowing the smaller spool to run at the larger diameter.

Please measure your own spool before printing, as 0.5 kg spool dimensions can vary between manufacturers.
