Creating PDF sewing patterns, stuck on printing it correctly

Hi community,
I have 12 letter sized frames that I have grouped together to create the sewing pattern on top of. The overlapping layers are all grouped together but I can not “split” the content into the 12 frames without messing up the overlapping layers and pattern. How can I do this so that the layers combine and split at the borders of each frame so i can individually move each one and print them as PDFs? Right now it only saves as one pdf which ruins the scale.
Thank you!!
