I designed this 16-segment display panel so you could print it even with the A1 Mini. It can show 4 digits, so you can use it as a calendar, or a countdown sign, but its made up of 16 small segments per digit, it's possible to use it to spell letters (I made a small dot cap so you could put it in if you want to use it to show letters).

I also made a simple box for the panel so you can use it e.g. to put an LED strip to illuminate the sign. It's a bit front-heavy when you put in the caps, so you might want to print the box anyway.

The caps with 0.1 mm offset fit in nicely, they're not too tight so it easier to put them in and remove them. But if you like them to fit snuggly, use the caps with 0 mm offset. You need to print the plate for the caps twice. One time in white and a second time in black.

The amount of segments you need to print:

horizontal segment: 24

vertical segment: 24

diagonal segment: 8

diagonal segment (mirrored): 8

small dot: 1

Total: 65 caps.

Don't forget to print the caps with both black and white filament, so that means total of cap= 130. I suggest to also print a small box to keep the caps in ;)

The download file for the caps and the box can be found under “Raw Model Files”

It's also super satisfying to put the caps in, its almost therapeutic. So if you don't want to use as a sign, why not use it as a puzzle box?
