My latest Marvin just finished printing about two hours ago. I’m really thrilled with the way it turned out - under close inspection I can barely notice any flaws in it. It was set to 100 microns, 205 degrees Celsius extruder, 55 degree bed, and printed on a Prusa i3 MK2 with Yellow Hatchbox PLA filament. (Just a word about this filament - I only got it two days ago, and have only printed two things with it - this Marvin and a nut and bolt combo - and it has blown me away. Absolutely stunning prints from it. Just bought another 5 colors of Hatchbox PLA!). Please let me know what you think!
