3dicons

3Dicons is a set of beautifully crafted open-source 3D icons that have been created in Blender and made available to the community. It has been released under a Creative Commons CC0 license, and hence it is free to use for personal and commercial projects, as well as copying, editing, remixing, sharing, and redrawing. This resource will make it easier for designers and content creators to produce beautiful and effective designs in less time. Although all icons are designed and rendered with a few color options to meet most of your production-ready needs, you can use these images as placeholders until you are ready to outsource a 3D illustrator.
