🧩3D Printing – 3D Printer Filament Manifold Adapter Model

A four‑way pneumatic quick‑connect manifold, a multi‑filament parallel feed splitter for 3D printers, and a universal feed adapter compatible with Tiertex/DIY extruders!

✨Model Overview

Featuring precision‑milled openings, this design incorporates a single‑ended DC male air inlet on one end and four standard pneumatic quick‑connect outlets on the other, enabling a 1‑in‑4‑out filament distribution. The port dimensions precisely match common 4 mm pneumatic quick‑connect tubing, while the one‑piece housing is ideal for retrofitting multi‑color, multi‑material parallel feeding systems—solving the cumbersome task of switching filaments on a single extruder. An essential DIY upgrade for 3D printing enthusiasts.

🔧Design Highlights

1. Precision‑Engineered Standard Ports: The air inlet and four outlet ports are modeled based on actual measurements of standard pneumatic quick‑connect fittings, ensuring a tight, leak‑free connection when directly plugged in.

2. Four‑Way Splitter Architecture: One central inlet feeds four separate outlets, allowing a single extruder to switch among four different filaments and enabling multi‑color or multi‑material printing.

3. : The compact, space‑saving form factor takes up minimal installation space, making it suitable for retrofitting desktop‑size printers.
