This is based on the Gunther style dock with a modular slot on the back for different USBC hubs.
I've made a module for my JESWO USBC Hub NC701.

Print with normal supports touching build plate only. the vent hole and text will print without supports. 2mm walls and skin, lightning infill at 15%
I've not printed this version yet but it is just a cut version of the full dock. (that I did print)
The author remixed this model.
This is a shorter version, printable on a smaller bed printer
