Mucha sgracias por las actualizaciones, pero al momento de imprimir uno de los archivos de la mano, detecte que no estaba escalada por default al mismo tamaño del brazalete, tengo las imagenes, desconosco cual es el factor de escala para corregirlo.

primeramente felicitaciones.
Me gustaria hacer una pero para mi tio. me podrias decir por cuanto lo deberoa agrandar para que sea de porte de adulto?

Firstly i would like to congratulate you on your magnificent work.
Could you tell me by how much i would have to enlarge it by so it could be used by an adult.
I would like to make one for my uncle.
He is in Chiule and I am going over there in a couple of days (I have two 3D printers at my disposal)

many thanks
