I have a friend that's asked me to print him a part for his American Harvest Oven that has broke. I'm thinking I'll have to do multiple process's to accomplish what I'm needing but not sure how to go about it to save some print time. From 72 to 83mm it needs to be 100% infill. Every setting I've played with shows between 13 & 14 hours. I've attached the factory file. Any help would be appreciated. Thx
