This is a tiny desktop PC setup. The side panel on the computer case can be removed by sliding it back (just like on a real PC) to reveal the components inside. It doubles as a tiny little secret box where you can store the mouse.
All parts can be printed without supports. To assemble the PC, slide the side panel onto the case; for the monitor, put a drop of glue into the hole on the back of the screen and insert the end of the stand into the matching hole.
The screen's inner dimensions are approximately 77.5 x 36.2 mm.
