This project represents the evolution of the classic 3D‑printable cable gland. By moving beyond the limitations of single-material designs, this innovative solution leverages the synergistic benefits of PLA’s structural rigidity and TPU’s flexibility to deliver a reliable, cost‑effective, and immediately ready‑to‑use technical solution.

Why Choose This Design?
The dual‑material approach addresses the primary challenge associated with 3D‑printed cable glands: achieving a robust threaded connection without compromising the cable’s seal.

Technical Features and Advantages:

• Optimized Bimaterial Design: The outer PLA body ensures precise, dimensionally stable threads with exceptional impact resistance. The internal TPU insert acts as a strain relief mechanism while providing a secure seal, delivering outstanding grip without damaging the cable jacket.

• Modular Versatility: The design is fully parametric, allowing for customization across a wide range of tolerances and dimensions, covering an extensive diameter spectrum. It’s the ideal choice for custom electronics projects, home automation applications (e.g., enclosures for ESP32/Arduino), and quick repair scenarios.

• Tool‑Free Assembly: Say goodbye to screws, adhesives, or complex post‑processing. The TPU ring is engineered for a perfect geometric fit within the PLA body—simply insert it and screw on the cap.

• Ready for FDM Printing: Geometries are specifically optimized for FDM printing, eliminating the need for intricate support structures and delivering clean, high‑quality results—even when using entry‑level printers.

Ideal Applications:

• Enclosures for electronics and IoT devices.

• Cable routing solutions for machinery or 3D printers.

• Rapid prototyping of wired systems.
