HAFC V3 – Hackman Automatic Filament Cutter

HAFC V3 HackMan Automatic Filament Cutter Smaller, more compact and more reliable! After the V2, I wanted to improve the design by making it more compact while keeping the mechanism simple and easy to assemble. The HAFC V3 is significantly smaller than the previous version, with increased trigger resistance to help prevent accidental activation. I've also simplified the assembly: the mechanism now requires only 2 screws, and most of the hardware from the V2 can be reused. What's New in V3? - More compact design – Significantly smaller than the V2.

- Improved trigger resistance – Helps prevent unintended activation.

- Simplified assembly – Only 2 screws required.

- Magnetic mounting – Uses 4 to 6 magnets.

- V2 hardware compatibility – Reuses the same spring, blade and PTFE fitting.

Hardware Required You can use a standard HAFC V2 hardware kit, which includes most of the components needed for this version. Qty Component

1 Bambu Lab filament cutter blade

1 Compression spring – 0.3 × 6 × 80 mm

1 M6 PTFE fitting

4–6 Neodymium magnets – 8 × 2 mm

2 M2 × 6 mm countersunk screws

If you already have a HAFC V2, you can reuse most of its hardware. Most V2 kits include 4 magnets. You can use those or add 2 more for the 6-magnet configuration.
