There are 40 emoji keychains for different situations. Not all have been tested on real print, if there is any problem please let me know so I can fix it. The scale of the objects is the way I thought it was ideal, increase or decrease it and test it to see how it looks. I cannot guarantee a perfect print on sizes other than the ones I have tested.
If you want to use it commercially, get in touch.

Layer Height: 0.2 Filling: 10% Nozzle: 0.4 Speed: 50 Printer: Anycubic Vyper Filament: ESUN PLA+
I used Cura 5 for slicing, I advise using this version because there are some functions that considerably improve the printing of small details, even with a 0.4 nozzle.
