Hi James,

Thanks for your response. I’m attaching the STEP file. Maybe you can correct the inaccuracies in it as I think I went for some generic components/packages.

My workflow was as follows:

1. Load up the PCB layout model into Kicad (downloaded from Github)
2. Hide all layers until I could easily the outlines for each component
3. Search and place each component’s 3D model using the PCB component properties dialog  
For step 3, I use Grabcad to find all of the component models. I deleted all of the .wrl files. I had previously tried the Blender route (open in blender and then re-save) but it didn’t work for me.
4. Once all the SMT components were placed, I exported the model as a STEP. This works surprisingly well.
5. Opened it in Fusion and got the rest of the through hole components and jointed them in
6. Finished off writing/colours

Hope this is useful.

Just to let you know, I’m using this for an educational robot that my company has built (version 3 of our Rover). We use this to run incursions and STEM clubs at high schools and stage 3 in primary. It has 4 wheel drive (parallel motor connections) using N20 motors and is powered with a 2S battery. The sensors are all Grove so are swappable. The custom PCB that we designed can take a Nano form factor microcontroller.

Many thanks
