I am not sure if this serves any practical purpose but I made it up anyway.
For me it is part of my iterative process of mounting the LCD in various places to find out what I like the most.
Two versions are here, one that slides in with an option to screw through an M5 (I think that they are M5s as I tested with the LCD panel screws and although it took some effort to tap the hole it worked.) and the other which uses a screw to lock on to the T-Slot, M3 should do the job.
Both require supports, sorry but I couldnt get anything I like without them. I printed with the model in the same orientation as it would sit in the printer.
