First attempt at a Fusion 360 project so not ideal but this is makes a useful package.
The Fusion360 file is a bit of a mess - I did lots of things wrong, unconstrained dimensions, references from wrong components etc. But there might be something useful in there if you want to tweak (includes drawings of components as well so you can view the whole assembly)
Input power via 5.5mm coax which can be 24V from Ender 3 v2 power supply or about 19v from a Toshiba laptop power supply. Two more 5.5mm coax connected direct to input so you can output to a laptop and a ts100 soldering iron at same time (if your input power supply can handle to wattage) and then output via a slightly more beefy (and slightly larger than most hence I couldn't use one of the existing boxes) Buck converter to USB socket and another 5.5.mm. Set the output to 5.1V for usb to power a Pi4. Or use the 5.5mm output, set to 16.5V to power a macbook pro (get a replacement cable off ebay and add the 5.5mm jack).
