There are four lights!
Step up to red alert. Sir, are you absolutely sure? It does mean changing the bulb

Well, I checked and the keyboard gerber files can be found on the ZX81+35 section of my GitHub entry https://github.com/mahjongg2/ZX81plus35
The same keyboard can also be used for my later design the ZX81+38
use it together with the keyboard overlay .PDF, which when printed full size on an A5 sheet should fit exactly, either with long stems through the circular holes in the overlay, or with short stems simply under the overlay (no hole cutting needed).
Now that I have returned to Github page I found that the ZX81+38 pages were missing a valid BOM (I seem to have not uploaded the real spreadsheet file), and omission I have now fixed. The BOM for revision 1.6 of the ZX81+38 is now available on my GitHub pages.

Is there a link for the ZXNU Project?
