First assembly...
The design was a bit of a gamble, there is a trade off between size, screen size, function, number of buttons, practicality, and so on.
it has worked out (a lot) better than I thought likely. The case is off-the-shelf about 16 x 9.5 cm, I mashed the keys a bit fitting it and it looks a bit tired,  I have to add trim etc and cut the case more accurately though.
There is a usb socket on the left had side for power ( the pico ) and serial ops/programming,  there is still space  in the case for a rechargeable battery for power.
Sorry for photo quality   , I hope it is of interest !
