cut of base swept

I Only have a 100X100 print area, I work with the cube scouts and they have a rocket launch coming up and The leader asked if i could bring some fun rockets It was a childhood hobby so i dug out the G sized ones and some cluster and than decided that i wanted a 3d printed one because i could and it interests the older kids. the fin assembly was to big so i cut it into two .
