Currently my plan is to use keyboard overlay (rub on) stickers, which should work, as the keytops are flat. With non flat keytops that would become impossible,
Not impossible just fiddly, those curved Alps keytops were a pain to do the rub on letters and symbols.
I can still remember doing it 38 years later, a good day was doing two or three key caps.
My ZX81 had what I now believe to be Alps keyswitches, no click but maybe 3-4mm travel.
My Microbees had nearly the same keyboards.
You would think it would be easy to make DIY keycaps these days.
Engraving flat keytops is probably the easiest.
Two ways I have used is the cnc engraving that uses two colour flat sheet PVC and laser engraving with two colout sheet acrylic.
Most trophy making places can do this, probably easy for the laser to even cut out the keys?
And lots of colour combos to pick from.
Those TACT type switches can get very tiring so perhaps the lightest force versions?
And maybe mount the whole thing with rubber or foam to allow some give?
Seen some DIY injection machines now, but still need a CNC mill to make the dies, DIY double shot keycaps?
DIY keyboards seems to have gone mainstream, bags of keycaps can be got in every colour now.
I have wasted days on this site
Apparently you can get testers with lots of diffrent keys, so you can choose the feel you like.
You can get wood keys and keyboards too, makes for easy laser engraving or even burning the letters by hand.
All because RPF brought out a mouse and keyboard I felt I had to learn about all this.
Pi's are more than just learning coding.
Soon I will be designing my next house around a nice Pi programming environment
I have already started on the furniture
Researching Manchester Victorian era upholstery patterns which led to learning something new or in this case old.

Lots to learn about their craft.
