Modular doorbell cover – Tecknet & other versions

This design was created as a protective cover for the Tecknet doorbell, but it also includes a 3MF file with additional profiles adapted to other doorbell versions.

The system consists of two parts:

• A rear piece for handling and wall mounting.

• A sliding visor moves along a rail and locks at the end with a small retaining ball. This retaining ball has a moderate tolerance, allowing for very gentle filing afterward to achieve a perfect fit.

• An optional TPU gasket for sealing between the model and the wall

A thin TPU gasket is also included to prevent direct contact with the wall or metal surface, reducing friction and avoiding loosening.

🔹 Fits Tecknet doorbell and other versions (extra 3MF profiles included)  

🔹 Two-piece modular design with rail and retention ball  

🔹 TPU gasket for secure, friction-free mounting  

🔹 Recommended printing on PETG or PETG-CF unless it is to be installed indoors (0.6 mm nozzle, 0.3 mm layer height)  

🔹 Compatible with 0.4 mm nozzle and other materials for indoor/outdoor setups  

🔹 If you use PetG-CF, I recommend finishing with a hot water wash and a metal sponge to remove any burrs

A durable, adaptable solution to protect your doorbell across different versions.

Important tip: File the adjustment ball very gently and try it little by little to make sure it fits perfectly.
