This is a universal Grivos mask. The model shown in the picture was printed on a Replicator 2 printer with a layer height of 0.15 mm and was colored with acrylic paint. The accompanying .x3g file is designed for MakerBot Replicator series printers, which is the file used for this print. Printing with this file took 4 hours and 53 minutes. Of course, we also provide the original STL file, so you can easily print it on other types of 3D printers as well.
