Fysetc Mechanical Filament Cutter — Tangle & Runout Protection

Never Lose a Print to a Tangle Again

The Fysetc Mechanical Filament Cutter is a passive, no-power tangle protection device that automatically cuts your filament path when a tangle or runout is detected — stopping your printer before a failed print can ruin hours of work. No electronics, no firmware changes, no fuss.

How It Works

The cutter sits inline on your filament path. When tension spikes from a tangle or the spool runs out, the mechanical trigger activates and severs the filament, signaling your printer to pause or stop. Simple, reliable, and always on.
