Here's a model of the "Spirit", a microphone by Aston Microphones that I have in my studio.
Since I bought this house, I've been creating and maintaining a 3D model of the rooms and what's in them. It comes in really handy for furniture buying (I can quickly whip up cupboards, shelves, etc. and then slide them around to see what fits) and decorating (I can color/paper the walls and take a look around in VR).
I've slowly been going through and getting through my studio equipment.
