š ļø Modular 150mm Ventilation System (Nipple Joint)
This is a complete, 3D-printable 150mm ventilation ducting kit. Itās a perfect solution for workshop dust extraction, portable AC venting, or DIY air circulation systems. The project is optimized for fast printing, material efficiency, and easy assembly.
The kit includes:
- Straight Duct (150mm): A standard pipe section with smooth internal walls for maximum airflow.
- Nipple Connector (Male-to-Male): Designed to slide inside the pipes for a clean, streamlined connection.
- 45Ā° Elbow: A smooth-bend radius to reduce air resistance while remaining 100% support-free.
š§ Assembly & Printing Instructions
This system was engineered with a "print-and-play" mindset, focusing on ease of use.
šØļø Printing Tips
- Use the Scale tool, unlock the uniform scaling (the lock icon), and adjust only the Z-axis. Keep the X and Y axes at 100% to ensure the 150mm diameter and nipple-fit remain perfect.
- Support-Free: The 45Ā° elbow is designed to be printed without any supports. Simply place it on one of its flat ends.
- Material: PETG is highly recommended for its durability and slight flexibility (crucial for a snug fit). Use ASA for UV resistance or PLA for basic, low-temp airflow.
- Wall Count: Use at least 3 walls (perimeters) to ensure the pipes are airtight.
- Infill: 10-15% (Gyroid recommended for structural integrity).
š ļø Installation1
- Nipple Joint Connection: Insert the connector into the end of the 150mm pipe. The outer diameter of the system remains consistent, making it easier to fit into wall mounts or tight spaces.
- Friction Fit: The tolerances are tuned for a tight friction fit. If you need a permanent, airtight seal for high-pressure extraction, apply a single wrap of aluminum or PVC duct tape around the joint.
- No Cleanup: Since no supports are needed, the internal surface remains perfectly smooth right off the build plate, preventing dust buildup.
