I wanted to build a rig for my sony a6500 and searched for a 3d model of the camera so I could design my rig better. But I didn't found a design, so I decided to design it my own and here it is.
I designed it in tinkercad.com - so I would recommend you going to that site and download it there (there you have more control over all steps I made to design it and don't just have the whole model as one piece - a bonus feature is, that it's colored), by visiting the following url:
