FAQ
120mm fan grill questions
Common questions about 120mm fit, free STL export, home printing, and using the browser editor.
What is Custom Fan Grill?+
Custom Fan Grill is a browser-based fan grill designer for 120mm PC fans. You draw, add text and images, preview your design in 3D, and export a print-ready STL file — no CAD software required.
What fan size does Custom Fan Grill support?+
Custom Fan Grill currently supports standard 120mm PC fans. Designs are sized for 120mm fan grills and 120mm fan covers used in desktop PCs, open-frame builds, and case mods.
Is STL export free?+
Yes. STL export is free for now. Download your 120mm fan grill STL and print it on your own FDM, resin, or SLA printer.
Can I 3D print the fan grill at home?+
Yes. Export an STL and slice it like any other 3D printing model. PLA and PETG are common choices for indoor PC builds; use thinner features carefully and follow the in-app design validation hints.
Will a custom fan grill block airflow?+
Your design controls airflow. Open areas and thin features allow more air through; dense artwork restricts flow. The live 3D preview helps you balance aesthetics and cooling before export.
Does it fit Noctua, Arctic, and other 120mm fans?+
Custom Fan Grill targets the standard 120mm fan form factor used by brands like Noctua, Arctic, Corsair, and Be Quiet. Always dry-fit before final assembly on your specific case or frame.
When will printed fan grills be available?+
Professional printing is coming soon. Pricing will start at $15 for the first frame, then $5 per additional copy, plus shipping calculated at checkout.
Do I need to install software?+
No. Custom Fan Grill runs in your web browser. Open the editor, design your 120mm fan grill, and export STL — no downloads or CAD software required.
