Need something like a Thunderbolt 3 splitter

    I have a 2017 MacBook Pro and an Apple Thunderbolt display. Connecting them is easily solvable, but it leaves me with a different problem. My goal is a true single-cable connection when at the desk. So with a Thunderbolt 3-to-2 adapter and an Elgato Dock, I can achieve that. But I'll use up both TB3/USBC ports on the dock, so should I ever want to add additional USB-C devices in the future, I'd have to connect to the MacBook directly instead of leaving them connected to the dock and therefore lose my single-cable design.

    What I'm looking for is some way to add a TB3 port to the mix. If the Elgato had 3 TB3 ports instead of 2, this wouldn't be a problem. Of course, I know it isn't like splitting a headphone jack, but that's ok. Searching around has not yielded anything that would help, so I'm asking here.

    If Henge Docks ever released anything promptly, that might be an option. A vertical dock from them would allow me to leave a USB-C a and Elgato dock connected to that. But it isn't available yet and probably won't be for another year given Henge Docks' track record. Plus, it's another $150 on top of the Elgato and doesn't allow me to use TouchID and the built-in screen.

    Their Horizontal Dock has the potential to be perfect if it ever releases. So I'm thinking I just wait, but wanted to know if anybody else had other ideas.

    On the plus side, most USB-C devices that you'd connect to the dock could just as easily be connected to a USB-A port.

    And most Thunderbolt 3 devices have another downstream Thunderbolt 3 port (e.g. if you wanted to add a Thunderbolt 3 hard drive to that setup, you'd connect it to the dock, and then connect the Thunderbolt 3 display to the hard drive. And you can keep going, so long as the display remains the final link of the chain). Then you retain the single-cable life.

    CalDigit makes arguably the best TB3 dock of all ( I have the non-plus model and love it. If you used that in combination with you could in theory hook up 3 monitors total over single USB-C port.

    Hot damn, that’s the kind of device I’ve been looking for. I don’t need so many monitors, but the dual USB-C ports is the feature I’ve been missing on the other docks. Thank you.
