It took a long while, efforts, expenses, and a full disassembly of my laser printer but here it is !
The look/aspect is great ! I had some little issues with the size (maybe due to slight resizing somewhere) and there are a few hicups with some mounting screws.
However the toner ink sticks rather well to the vinyl sheet and glueing didn't leave bubbles. The alu face plate can remain (mostly) clean and it adds a lot to the ergonomics :-D
Locating the "right" plastic sheet took a while...
And here it is in all its glory !
All the switches are soldered but the assembly/wiring is not complete, I need to add another board to really get all the signals together. So I created a small board with 16 Glühbirnchen to ease the tests :-)
