This is a Raspberry Pi 4 created from the official Raspberry Pi 4 DXF file found at the following link: https://www.raspberrypi.org/documentation/hardware/raspberrypi/mechanical/README.md
I created it as a mock up for some projects I am working on as handy to have a working model for assemblies. The STL and STEP file are uploaded here.
I basically extruded the ICs and few of the larger components, then added and placed best fit 3.5mm jack, USB-C, Micro HDMI, USB 3 and Ethernet connectors.
Should prove useful for anyone making a project with a Raspberry Pi 4 so they can prototype the assembly before actually printing.
The images show the process and how everything is aligned, the models used for the 3.5mm jack, USB-C, Micro HDMI, USB 3 and Ethernet are not the exact same as the official board, but they are a very close fit for where they protrude from the board edge. The USB 3/2 connectors can clearly be seen to extend further into the PCB than the original footprint, so be aware of this.
I could have gone around and added all the components pins etc, it would have made it look very nice, but little point from a practical perspective.
Hope it proves useful....
**Worth reading the comments about the Ethernet and audio jack.
