Bueno tras muchos intentos he conseguido modelar con blender el fichero .stl para imprimir en la impresora 3d un rodillo texturizador similar a los de GreenStuff, si se quiere la textura mas pequeña solamente escalando en Z se consigue, eso si tendremos un rodillo mas pequeño y se imprimira mas rapido.

After tons of tests, I modeled with Blender an succesful textured roller pin, suitable to be printed with 3d SLA printer or FDM printer it depends of the quality you´re looking for!!!, I used an tileable texture of cobblestone road, improved with Photoshop. Stl tested on meshmixer and reescaled correctly, If you would smaller just scale it in Z with your slicer., will print faster than the master.
It will be great if you send pictures of the stuff printed.

Agradecimientos a Soliman de Foro3d por sus consejos y a Craft Logic que es el autor del tutorial en Youtube, realmente inspirador.
