A create a keychain label with interchangeable inserts.

Multicolour without having an MMU :).

You can coustomize the text with prusaslicer, just open like a project the 3mf file, and edit the text.

You can print the insert with residual filament, is 2grams and 67 cm of filament used for one insert. Don't trow away your remaining filament, print inserts for your ultimate keychain :)

Enjoy
