If your printer is built on the most common 2020 aluminium extrusion profile this LCD case could be a very good fit.

2 Versions: 0ne and two switches. Power and eg. LED.

Total dimensions: 155 x 65 x 100 mm (l,w,h)

Switch hole 19 x 13 mm (I use this one: https://www.aliexpress.com/item/4Pcs-4Colors-DIY-21mm-15mm-Indication-Rocker-Switch-illuminated-250V-AC-ON-0FF-Power-Button/32807408135.html?spm=a2g0s.9042311.0.0.vCJdBD )

Hence it where two displays to mount I realized that every display is slightly different soldered. You might be forced to push it a bit.

I did a bunch of prototypes to get the best accurat design, Holes fit perfectly to mine.

Knob was taken from https://www.thingiverse.com/thing:320117 Thanks schlotzz!

For the text ink I used a POSCA pen. Search for it or ask your kids ;-)

Appreciate if you decide to pimp your printer and controll your destiny with that nice LCD pannel :-)
