I modeled this toy with Blender and textured it in Substance Painter 2. This was my first Substance Painter experience. I used the Linux release under Ubuntu 16.04. Works like a charm^^ The model is free to download @Sketchfab inclusive PBR textures.
I love it man! Love the texture and material of it. Definitely has a nostalgic feel to it. For sketchfab it’s fine but I could suggest maybe having a floor on the image one so that it seems more grounded and not floating in space. Besides that, very nicely done! Have you thought about animating it?
