Triangular key for Gewiss electrical panels

Material: PETG HF

The use of PETG HF is an excellent choice for this application. PETG offers superior mechanical and thermal resistance compared to standard PLA, ensuring the triangular socket does not deform under stress. The "High Flow" variant allows for higher printing speeds without compromising layer adhesion, resulting in a robust and functional component.

Shape and design

Ergonomic grip: The key features a wide, winged "T" handle. This design provides ample surface area for the thumb and forefinger, allowing for a comfortable grip and easy lever application.
Triangle socket: The end is made of a cylindrical shaft with a precisely recessed triangular female socket.
This geometry is specifically designed to interface with the standard triangular cams found in Gewiss electrical panels.
Integrated key hole: The handle includes a small through hole, making it easy to attach to a key ring or hang inside a utility room.

Usefulness and functionality

This key is an essential tool for electricians, maintenance workers, or homeowners. Its primary function is to unlock and lock electrical panel doors.

Safety and protection: It ensures that sensitive components (such as the RCD shown in the photo) are protected from accidental contact or unauthorized tampering, while remaining quickly accessible for maintenance.
Perfect fit: The 3D-printed dimensions are custom-made to meet Gewiss standards, ensuring a perfect fit that prevents the plastic or metal cam from breaking.

Minimum material: Printing requires just a few grams of filament, making production costs almost negligible.
Quick delivery time: Thanks to the compact size and use of high-flow filament, printing can be completed in a very short time.
Availability on demand: Instead of ordering a replacement part and waiting days for shipping, you can have a fully functional tool ready to use at home or in the office almost instantly.

This 3D printed tool is a practical example of how additive manufacturing can solve everyday problems with minimal resources.
