Export to STEP gives just the board outline and drill holes 1.6mm thick. I was able to convert the STEP to an STL in FreeCAD and print the first few layers so I had a rigid sheet I could attach the connectors to in order to get accurate spacing and also check the position of the mechanical mounting holes. It took about 4 iterations to get everything right, but saved me sending off for boards which won't fit.
Some more KiCAD goodness

Some more KiCAD goodness
I recently ordered a random VCU case from aliexpress (this one https://www.aliexpress.com/item/4000115814857.html), it was of course completely undocumented and unfortunately I couldn't get my calipers to fit to give me the required measurements. This is when I discovered a couple of excellent features available in the PCB design part of KiCAD.

It took about 4 iterations to get everything right, but saved me sending off for boards which won't fit. When I discovered this I thought I'd have a look at what else I could get out of it. Export to VRML of Johannes V3 board (screen grab from FreeCAD) The VRML file pushed through meshconv (https://www.patrickmin.com/meshconv/) to convert to an STL then loaded into CURA. I've attached the VRML and STL below in case anyone has any use for them.
