this is my 100% definitely not a laptop laptop
the weird cut outs in the steam deck holder are just cause I'm new to fusion. (ignore those it still works)
would recommend attaching parts with a strong glue and a soldering iron.
you will need to find your own hinges. (3d printed ones work fine just look for big ones on Thingiverse)
the hinge stopper attaches to the back of the screen to wedge itself between the screen case and the main body (it helps to remove some stress from the hinges)
designed to work with a 27in screen
most 60% keyboards fit fine (less the 11cm wide)
you can fit a track pad but with how bulky this is just use a mouse.

you may ask.
"a steam deck is not meant to be a laptop."
or
"your defeating the purpose of the steam deck"
