Custom background colour
Free download of an isometric 3D transponder icon, ideal for aviation, tracking, communication, and technology visuals.
A free isometric 3D transponder icon for aviation, tracking, and communication themed designs. Useful in apps, dashboards, transport systems, and technology presentations, this icon represents onboard signaling and identification equipment with a clean, modern isometric style that is easy to download and use.
Every Transponder detail is modelled at the same scale and lit the same way as the rest of Thridy's 3D icons, which is what keeps a set looking deliberate. It is an isometric 3D render, on a transparent background, with no mask to draw.
It suits aviation, tracking, communication and technology visuals.
Sizes on offer are 1024, 512 and 256 pixels, free for personal and commercial projects with a credit to Thridy. Download it free, or request a custom variation if your project needs a different angle, colour or companion icon.
Free for personal and commercial projects. On the free plan, credit Thridy wherever the icon appears: a website footer, video credits, an app's about screen, or a README.
