Description
This is a 3D-printable replacement key designed for outdoor water taps / wall hydrants, specifically modeled to fit FM Mattsson (FMM) valves and other brands using a square socket.
Losing the original brass key is common, and this printable version serves as a perfect, high-strength replacement for your garden or driveway tap.
Features
- Perfect Fit: Designed for the standard square spindle found on most Scandinavian and European outdoor faucets.
- Ergonomic Grip: The handle is optimized for a comfortable grip, providing enough leverage to open even stiff valves.
- Reinforced Design: Extra material around the socket to prevent stripping or snapping under torque.
Printing Recommendations
To ensure the key can handle the torque required to open the valve, I recommend the following settings:
- Material: PETG, ASA, or ABS (PLA can work but may be too brittle for very tight valves).
- Infill: 15% (use "gyroid" for extra strength).
- Walls: 4 perimeters for maximum structural integrity.
- Orientation: Print it lying flat or with the socket facing up for the best layer strength.
