Air Straightner Mesh Block (Set of 2)

Creating an Air Straightener Mesh Block can be a tedious process, and you’ll need additional materials to make it work effectively. This ready-made mesh block is designed to simplify that process—no extra materials or assembly required. I designed, 3D printed, and assembled it myself to help improve laminar airflow for model car wind tunnel tests. All you have to do is create an enclosure for your own DIY wind tunnel, and you're ready to go!

What's included in the package:

• Air Straightener Mesh Block x2

Block Dimension:

• 4.72 x 4.72 x 1.18 inches (120 x 120 x 30 mm) compatible with most 120mm fan

While I’ve carefully designed this product for stable, realistic airflow, performance may vary depending on setup, environment, and equipment. This mesh block is intended for hobby use only, and users should handle and install it responsibly.

The fine mesh is highly effective at straightening airflow, and the block measures 120mm x 120mm x 30mm, fitting most standard 120mm x 120mm desktop fans. Each set includes two blocks—one for the front air intake and one for the rear PC fan—providing a complete setup for improved airflow control.

With these ready-made mesh blocks, you can skip the DIY struggle and jump straight into testing. It’s simple, durable, and designed to integrate seamlessly into your wind tunnel setup!
