This 3D-printed junction box for WAGO 221 connectors is a simple yet highly practical design that solves a real-world wiring challenge with elegance. The compact form factor keeps the connectors securely aligned while providing a clean and professional installation appearance.

The integrated mounting holes are particularly useful, allowing the assembly to be fixed to a wall, panel, or enclosure without additional hardware. This transforms standard lever connectors into a tidy, organized wiring solution that is much easier to manage and maintain.

From a 3D printing perspective, the model is very well suited for FDM printers. The geometry is straightforward, requires no complex supports, and prints quickly while remaining robust. The rounded edges and precise connector openings demonstrate thoughtful design and attention to detail.

The bright color also makes the junction point easy to identify during installation or troubleshooting, which is an added practical benefit. Despite its simplicity, this holder significantly improves cable management, safety, and overall aesthetics compared to loose connectors.

A clever, functional, and highly useful accessory that showcases how 3D printing can provide custom solutions for everyday electrical projects. Perfect for makers, electricians, DIY enthusiasts, and anyone looking for a cleaner and more secure way to mount WAGO 221 connectors.
