Giants helmet for all to print. Printed great first try for us. If you trust your printer to speed up the print go for it, these are just the speeds we use. I know the back can be printed faster easily, its just set to our face speeds on the 3mf so it says it takes 4 plus hours if you slice it without changing anything. Make sure you heat up and clean your nozzle of any old filament stuck to it before starting the print to prevent color wisps from left over filament. Enjoy and Happy Printing!
