This is a stand for a Raspberry and 7" LCD with touchscreen (18cm viewable diagonal). If you need another dimension, look into my other designs with 4,3" and 3,5" LCDs.
This LCD has the following dimensions:
165mm x 100mm x 7,5mm
You need M4x20 bolts and nuts for the ribs and ~M2.5 bolts to mount the raspberry.
The HDMI connection is ugly, I know, maybe I will figure out something better.
You can again optionally print out the audio-part which holds the PAM8403 PCB (22mm x 22mm) and a small speaker (diam.28mm x height: 3mm).
