### English Versions:

I needed a triangular standard key to be able to open a gas meter box and a garbage bin.

I've found multiple triangular key designs but none of them specified any dimensions, so I made myself some different models so you can know what are getting.

All of them have a diameter of 15.5mm and there are 4 different versions (the only thing that changes are the triangle side lengths):

-10 mm
-11 mm
-12 mm
-12 mm with 1 mm cuts on the vertices

I've printed all without support. If you'd like a different size, just let me a comment and I'll upload it.

Hope you like my designs!
If you found this design helpful, feel free to tip me a coffee. It's always appreciated!

### Versión en Español:

Necesitaba una llave triangular para abrir el contador del gas y para cubos de basura.

He encontrado distintos modelos de llaves triangulares pero en ninguno especificaba las dimensiones, y no me iba a poner a imprimir todos a prueba y error.
