(Original Prusa parts can't be referenced to give proper remix credit)

I extracted the part of the R1 printable front Y-axis plate that the display mounts to, including the adjustment detents.  It's been made more-presentable by mirroring the “thin rim” feature so the top and bottom are symmetric.

(Display signaling does have a cable-length limit--a 50cm-long ribbon cable is sufficient to exit the MINI enclosure. I started with this one: https://www.amazon.com/dp/B07S1W1KW3?th=1 )
