The Khronos Group has uploaded yesterday 3D versions of some logos: Vulkan, WebGL, glTF and SYCL. These logos are, of course, in glFT format and are PBR-ready because they come with albedo, normal and occlusion/roughness/metallic textures.
You can download these 3D logos from THIS PAGE.
Update (2018.09.18):
You can also download all 3D logos from this link:

I quickly tested these logos with MadView3D, a simple 3D object viewer coded with GeeXLab.
Are these logos still available in glTF format? I can’t find them in the Khronos website.
Yes looks like Khronos has removed them all. I will upload them on geeks3d server asap!
