New to 3D printing and I wanted to print a giant nut, specifically the battlebots nut so that I could copy it in silicone and remold it multiple times in pourable plastic (that's more my domain) what I didn't know is the nut needed to be printed with 100% filler and I only used 10% to save on pla, this nut is 250 mm wide X 100 mm tall. And used an entire 2kg roll of pla in 48 hours. So since it required a 100% fill the top of the nut is still open. I left it sitting on the bed untouched. If I upload my gcode is it possible there is someone that can write me a simple code to cap the top? I am at work now so I dont have the gcode with me. But I do have a picture of the nut. Thank you in advance.
