@foone I think almost what you described later in the thread:
- bought USBC monitor.
- pre-existing bluetooth keyboard.
- measured things (badly).
- CAD slab with holes for things + sucky hinge.
- order 3d printed CAD things on the interwebs.
- oh no holes not measured properly, time for hot knife surgery!
- glue monitor to 3d printed pieces with some random glue that looked strong.
Phone is a Samsung that has a Samsung DeX thing built in, and I run termux with an Arch emulation layer.
