Motivation
This 3D model was designed to facilitate a more ergonomic connection between a portable AC's corrugated pipe and the recuperator hole. The goal was to achieve a comfortable angle, thereby conserving the length of the pipe and ensuring a more space efficient setup.

Design Highlights
The model has been engineered to be resource-efficient, reducing the amount of filament needed. Internal structure allows the model to be self-supporting.

While slicing you have to add support only for horizontal part.
Printing recommendations
- Nozzle Size: 0.4 mm
- Layer Height: 0.2 mm
- Layer Width: 0.4 mm
- Infill Pattern: Any (recommended density: 15%)
Material Considerations
Please select your printing material based on the operational temperature conditions. PLA is not suitable for high-temperature applications as it may melt and deform. PETG is recommended for its higher melting point and durability, which I have found to perform well in my experience.
Customization Guide
The model is designed to be adaptable to your specific requirements. Below are the parameters you can adjust to fit your setup:
- d_hose: The external diameter of your corrugated pipe.
- d_hole: The internal diameter of the hole you wish to connect to.
- l_hole_joint: The length of the joint to the regular pipe side.
- l_hose_joint: The length of the joint to the corrugated pipe side.
