I recently built an amiga 1200 in one of the a1200.net replica cases, and bought a little generic 10" LCD off of amazon (Hikity brand; https://www.amazon.com/Hikity-1024X600-Resolution-Compatible-Surveillance/dp/B077FSR36B) to use with it. the 10" LCD is a great size to sit on the air vents behind the keyboard, and I thought it would be fun to build a custom mount.
to install, remove the metal plate from the bottom of the existing monitor stand, then connect this plate to the base of the stand with the alignment pegs poking through the holes, and hold it down with the original screw.
not a derivative or remix of https://www.thingiverse.com/thing:3611198 but I did borrow a couple of measurements from it instead of taking them myself, so I wanted to give the original modeler a shoutout.
edit: updated to make it lighter and block less airflow. also, I found that if you print it on end with a brim, the surface comes out much better than if you print it laying on one of the flats as I originally suggested.
The author marked this model as their own original creation.
