Not everyone is an illustrator, and that's okay. The internet is full of generous creators who share high-quality vector assets for free. The key is finding files that are "clean"â€â€meaning closed paths and no messy overlapsâ€â€so they extrude perfectly in Vextrude.
1. SVGRepo
Best For: Everything
Over 500,000+ open-licensed vectors.
SVGRepo is arguably the best resource for 3D modelers. Why? Because most of their icons are "monocolor" paths, which means they are usually single, solid shapes. This makes them perfect for extrusion without any cleanup.
2. Simple Icons
Best For: Brand Logos
Thousands of popular brands (Twitter, Facebook, etc).
Need to make a 3D Facebook logo or a YouTube play button? Simple Icons provides canonical, color-coded SVGs for almost every popular brand. The geometry is always optimized and clean.
3. Undraw
For more complex scenes, Undraw offers open-source illustrations. While these are more complex, you can often ungroup them in a vector editor and extrude specific layers (like a character or a background element) to create a "diorama" effect.
4. Feather Icons
If you are designing 3D user interfaces or physical buttons, Feather Icons is the industry standard for minimalism. The strokes are consistent, which means if you convert strokes to paths, you get uniform thickness perfect for 3D printing.
5. Google Fonts (Icons)
Formerly Material Icons, this massive library offers thousands of consistent symbols. They are perfect for 3D printing functional signage (like "Restroom", "Exit", or "Warning" signs).
