Raspberry Pi 4 case with break-out GPIO tab + fan versions

UPDATE 17/05/2020 - Receiving requests for files so added all F360 document files and STEP files. The F360 files might be a little bit of a mess with the workflow and I didn't name everything so might take some picking apart. Sorry, it was my first year learning design. There is an F360 file for a multi material model. the top half has been split into sections, just the bottom half needs the same to finish it off. I just don't have the time.

The model I've printed, I use a filament change (M600) to make the top and bottom different colours. Multi-part model coming soon for people with dual extruders/MMU/Palette

Inspiration for the layout came from my favourite Pi 3b on here (https://www.thingiverse.com/thing:3714695), and the Pi 4 remix helped getting the ports lined up first time, so thanks for that.

For the GPIO to break out, make sure "Detect bridging perimeters" is unchecked in PrusaSlicer under Print Settings->Layers & Perimeters
