I'm trying to fit 9 hexagonal items onto my print bed and it is only allowing me to fit 7 of them with the arrange all models option. If i play around I can fit up to12 of these items onto my print bed with adequate spacing, but only 9 is needed. Is there a way to adjust the spacing tolerance for the Arrange All Models feature? Yes, I know I can manually just rearrange things but I am going to have to do this for every print and I need to make about 30-40 different batches. Changing this would save me a large amount of time.
