Bronze key caps, commonly used in Argentina.

These are the models I've made over time.

These are designed with the use of PLA in mind.

After printing, glue the two parts together.

They can be used for 1 to 12 months, depending on the wear and usage.

It uses very little material, just a few grams.

If I receive enough comments, I think I'll make more, improve the model, or try to make customizers.
