Yes please.
In theory, there is no difference between theory and practice. But, in practice, there is.

Hi guys... reworked everything so should ( but have not tested ) be an easier fit.

not very good with this dropbox thing but...here goes STLS
https://www.dropbox.com/scl/fo/jpcsm9e8 ... bsbs6&dl=0

print faceplate with bobbles up, and print case with the open end up.

also Tinkercad links

case https://www.tinkercad.com/things/eOrypM ... m4VSRKnJj8

regards Andy

Edit :- think i fixed the tinkercad links...

I've spent an hour desoldering the keys on the first board, and it looks like it's going to work, however I did spot why Andy put in the little riser blocks (great catch Andy!)

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

of course the simple solution would be to order the right key switches with the location pegs... :lol: :lol:

looking forward to seeing your progress and how those clear top keycaps work out.

Ok, so the reprint went well - so reprinted in black.
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...

@system11
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

Messages only leave the outbox when the recipient actually reads them.

I'm looking at taking a different route to Andy - incorporating the full keyboard into an enlarged zx81 case.

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.

I should probably move this to a different board but here's my first (draft - lower quality printing) attempt at the top of what I'm calling my ZXtended 81
