A simple little wedge to mount the display from an Ender3 V3 KE horizontally. I switched to GuppyScreen on my KE, and needed a 90 degree-turned holder, but I was limited because I'd added some supports that got in the way of other models.
Put this together in Tinkercad in a couple of hours, fits fine, does the job. Just needs 4 rubber feet.
No supports needed, print in whatever.
The author marked this model as their own original creation.
