I didn’t be able to be brave enough to buy a real one so I’ve made a toy VW T3 camper bus. Here are some images and the STL files for 3d printing.

Below are the parts as a whole in a single STL file for you to print. If you don’t have a 3D printer, here is the link to shapeways.com where you can buy a printed one online.
