The Framework Laptop will only provide 5v. Laptop ports are just not meant to be a high-power supply.
Framework laptop USB ports support Power delivery.
They support USB PD input, not high-power output.

Iād want 1, no hesitation. Charge what theyāre worth, donāt sell yourself short.

Iād say worry about PD later ā¦ Maybe a gen 2 addition?

I second that. If you want PD, youāre better off using a powerbank or a USB power supply nowadays.

Iād say screw pd in this case. Having pd would require power muxing and a buck converter for the second port which is going to be tricky to fit and probably relatively power-hungry for very little gain.

As of right now, how much do you expect it to cost for the parts, assembly, and shipping?
Do you have any plans for a 3d-printed metal case?
Excuse me, where can I get affordable metal 3D prints?

Iām ready to buyā¦ anytime.
For real, I have a use case for this already and would like to compensate you for all your engineering and development.

Similarly, without wanting to make this a thread of people repeating the same things, Iād be interested in purchasing one of these with its current features.
When I find myself short of type C ports, it is usually because Iām plugging in more low-speed, often short-term uses, things like hardware keys, transmitters for presenters, wired keyboards/mice, simple audio interfaces, etc. These donāt need more than standard 5V/1.5A, and donāt need more than 3.1gen1. Having one of these expansions would mean that those devices wouldnāt need to take up the fully-featured ports.

Iād love to buy some of these! Donāt need PD, or anything else, just USB 3.1 gen1, thatās it, that would be fantastic!

I did just order a few very simple USB-PD chips to experiment with. It could be implemented with very few components (like the IC and two resistors for minimum configuration), also itās quite small and fits into the unpopulated area on the daugther-board, so the FW handles the 3A over to the hub, instead of the default 1.5A (thanks @Josh_Cook for pointing that out 
), which could be a bit low for connecting two devices).
The chip will only negotiate the 5V/3A from the laptop to the hub, so still no charging option.
I also did fix an error in the schematics of the main board (the supply for active cables was incorrectly wired).
Iām getting a few bucks tax-money back this or next month, Iāll probably invest that in a few assembled boards once I did iron out things and got the PD-thing running.

The dev-boards for the PD-controller I designed and ordered are here . It works fine convincing the framework to handle over 3A with the PD controller. For the next revision Iāll add the PD chip on the daughter board .
Thatās how these simple boards look like:
The chip in the center is the one handling the PD (itās a HUSB238, in case someone is interested in details).
I assembled three different configurations, the framework only can handle 5V but I wanted to try some other voltages for using them with USB-PD supplies. The other two are 9V/2A (thatās what for example iPad chargers use) and 15V/3A.
Itās quite simple to use the chip, it is programmed by two resistors that set the voltage and current it should request. There can also be programmed some more advanced things like fallback voltages and stuff by an external interface to a microcontroller, havenāt tried that yet tho (the white connector is for an I2C bus).

Might be a stupid question but how are you fitting everything with the PD board into an expansion card shell?
He only needs to fit one black chip and two resistors.

Awesome what max wattage would it support?
And a P-channel MOSFETā¦ I checked the datasheet ā¦ a pretty cool chip ā¦ The MOSFET also needs an additional 2 resistors ā¦ lol But an impressive feat non the lessā¦
I would think you only need a MOSFET if you have need for overload protection. But the laptop should already have that upstream.
