Edit :- think i fixed the tinkercad links...
I've tweaked mine to add the little risers (I'm definitely ripping off your design here - not intentional but as the saying goes, imitation is the sincerest form of flattery!)
I ran out of black filament (some due later today - Thanks Amazon Prime!), so I'll give it a try in white to see how it looks
looking forward to seeing your progress and how those clear top keycaps work out.
I also made up a blank to go on the rear side as tbh I quite like the minimalist look for this one as you'll see on the image.
The clear key-caps seen to work ok - it took me bloody ages to get the keys right for printing - I scanned a standard keyboard membrane and spent ages retouching each key to be a bit more visible - I think it shows!
Anyway - here's my attempt...
Yes - I still have a keyboard PCB available, and due to buying another Minstrel 3 PCB, I have a ZX81+38 PCB available too
I've tried PM'ing you but my messages are just getting stuck in the outbox - they don't seem to be reaching you
I've been playing with Tinkercad and this is where I've got to. I know that the '81 motherboard (actually it'll be one of Mr Curran's finest Minstrel 3's) will dictate how the base is laid out - I'm expecting the expansion cut-out to be more in the middle of the case than on the right hand side. It's a work in progress and so far I've JUST managed to get it to stay within print boundaries of my 3d printer.
