Cervical Dilation Practice Rings

These are cervical dilation practice rings I made for my wife who is a labor and delivery nurse. She has to call out how dilated a woman's cervix is so they can track how close the patient is to having the baby.When trying to print these, if they appear super tiny in Cura or whatever slicer your use, scale them to 1000 and they should be good.I've printed a few sets now and can attest to their dimensional accuracy.My wife loves them and she says they have made her much more accurate at calling the right numbers of dilation.Hopefully this can help other nurses or doctors who have to do the same thing.
