Description
The Felfil Spooler+ is a precision filament spooler for universities, R&D labs, and makerspaces that already own a compatible extruder. Its high-precision optical sensor continuously measures and auto-corrects filament diameter during spooling — available from 3DCraftMakers, the authorized US Felfil reseller and distributor.

Standalone precision spooling — integrates with any compatible extruder
Set a target diameter, select a material mode, and the Spooler+ manages everything else. The optical sensor samples filament diameter in real time and adjusts puller speed automatically — producing consistent output without manual intervention.
Works with the Felfil Evo Extruder or any compatible extruder outputting 0.5–3 mm filament. Soft polyurethane rollers protect filament integrity across flexible and brittle materials alike.
