This STL file contains the 3D model for a perforated NACA vent grill insert designed to fit the standard Van’s Aircraft NACA vent used across RV-series experimental aircraft. The insert features a 1/8" hole pattern optimized to block nuisance insects—such as hornets, wasps, and other small pests—from entering the ventilation duct while maintaining smooth, unrestricted airflow. The model is oriented for easy printing and is intended to be produced in ASA or another UV-resistant, high-temperature filament suitable for aircraft environments. No supports are required for printing. Perfect for RV builders and experimental aircraft owners who want a lightweight, clean, protective solution for their NACA vents. STL LICENSE & USAGE TERMS (Applies to All Products) By purchasing any STL file from this store, you are receiving a personal-use license for your own aircraft project. You may 3D print the file as many times as needed for your individual build, but you may not share, resell, redistribute, or upload the digital file or any printed versions. Commercial use of any kind is strictly prohibited, including but not limited to: Selling printed versions of the part Providing the part or file to others (paid or unpaid) Using the design in kits, bundles, commercial aircraft projects, or reseller platforms Posting or distributing the STL in any online repository, group, or forum Purchase of the file constitutes agreement to these terms. LIABILITY & USE DISCLAIMER (Applies to All Products) All STL files and resulting 3D-printed parts are provided as-is, with no warranty, expressed or implied. By purchasing, downloading, or printing any STL file, you acknowledge and agree that: You are solely responsible for selecting appropriate materials, print orientation, infill, print settings, and final part quality. You assume all responsibility for determining whether the printed component is suitable, safe, and airworthy for your specific aircraft and installation. The designer/maker assumes no liability for any damages, failures, injuries, losses, or issues arising from the use, misuse, modification, or installation of the part. These designs are intended for experimental, amateur-built aircraft, where the builder is responsible for all fabrication decisions and safety evaluations. You must verify fit, function, and durability before installing any printed component in your aircraft. Use, download, or purchase of any STL from this store constitutes acceptance of these terms. Because 3D-printed components vary based on the user’s printer, filament, and settings, always inspect, test, and validate the print before installing it. Print performance may differ from the parts shown in my videos due to differences in materials and equipment.
