I want to know too so I can perfectly center the 6-axis sensor in my staff! (which is coming together, just got some 21x12mm O rings to keep the strips in the center of the acrylic tube shaft!)
@wizard is out at a conference right now, but I tried to make a real rough one for you guys quickly.
I started from the open source .BRD files for the existing Pico we see here:
I converted it from a 3D PCB to a 3D model by exporting/importing to/from .STEP.
Then I made some very rough adjustments to the bodies and components - a quick glance will show you it’s not that accurate and it’s not a clean parametric design, but the outline, height, holes, light, and button should be accurate enough to design an enclosure (those are the components I’m usually modeling around). I also marked the IMU (accelerometer) in red and moved it’s centroid to the origin, so hopefully these are the axes you’d be measuring movement around.
