Cross Stitch thread organizer

Hello I made this to organize my thread for cross stitch since the card stock one I was using broke.

I scaled the non separated print to 10.5 in long
Making the separated print 5.25 in long each

I have included both the blender file(non separated file) and the split STL file.

I used a resin printer for this so I'm not sure how a FDM printer will interpret it.
