Custom background colour
Free download of a plus sign 3D UI icon in a premium front-facing style, perfect for add actions, interfaces, buttons, and app design.
A premium front-facing plus sign 3D UI icon designed for add buttons, create actions, expandable menus, and interface controls. Its clean non-isometric style fits modern dashboards, mobile apps, websites, and design systems. Free to download and easy to use in polished UI projects.
The Plus Sign icon is a front-facing 3D render with soft studio lighting, gentle shadows and a silhouette that stays readable from a hero section down to a 48-pixel UI slot. It ships as a transparent-background PNG, so it drops in without masking or background removal.
Because every icon in the set is rendered the same way, the Plus Sign icon sits comfortably beside the rest of UI & Interface when you need a matching group rather than one image.
Designers reach for it most in landing pages, mobile app interfaces, presentations, infographics and social media graphics, and it suits startups, agencies, product teams and content creators. 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.
