from looking at it, the sd-slot seems to be on the wrong side, but maybe the parts can simply be switched.
still, could lead to confusion.

The sd slot should be right, I just ordered it on the right side instead the left where it belongs on the design sheet. But I will check again.

exactly, it is on the screen side, not on the encoder side. this brings the next question, what about the display "hole" do people make that on their own? probably a stupid question, but it does not display a hole here for the display.

I don't know exactly what you mean. The SDcard slot will be on the left side a bit in the direction of the connection panel. It is designed to fit if the display is soldered nearly up to the top side. I made the slot anyways a bit bigger if somebody has soldered it already a bit lower. If I see it correctly, it is so big, you can place the display with the stackable headers completely down the PCB or completely up to exactly beneath the acrylic control panel.

Yes I could place it on the other side, but I think people with an FM synthesizer will be smart enough to connect together 6 simple parts correctly ;) If not, it's simple to remove and replace those parts.

And as described in the readme file, there are 4 versions: 2 for small buttons (with 3d printed adapter) with and without LCD window and the same for the bigger buttons like from the Ambika.
You can see the blue lines making a window in the 2 files with ending names "Windowed" or not ? These lines will be cutted by laser/mill. But you do not need the window, if you use clear acrylic. Then you would
take one of the versions without "Windowed" in the filename.

Makes sense, all good! I was confused because some files did not show the blue lines for me at all with svg, so when I opened the pdf I only looked at the one that was working before and hence never saw the lcd window...

Not yet... I created a version of the top that is good for drilling (finding the middle of all the holes) and printed it. It seems to align well. Will take some days before I find the time to do it...

There it is:

I had no time to put the PreenFM3 into it, but I will make this later.
The only complain is, the factory made a failure with the label alignment, so all letters are shifted 1-2mm. I mailed them and will see what they say.

And here it is with the PreenFM3 mounted.

I have to say, the letter printing is not only wrong aligned (factory fault as what I can see).
Also it is a bit weakly printed, I used grid engraving. Maybe I should have used vector engraving for this, I will check. But no problem, as you can paint it easily with acrylic paint. I also managed to fit the power button hole and you can put on the line out protectors if you turn every 2nd one to 180 degrees.

That's really cool.
Congrats for pushing this project to the end   :)

I didn't follow the file format story. Are pdf or svg available ?

Thanks, PDF is inside the archive file. I will also reimport the SVG file from the factory side, that should work. Wait till 20H today I will upload the new file.
