About this 3D model
This is a chemo port scaled down for a 18 inch doll. It is a 2 part print. The first file is the body and the other is the center and outer circles. The model is full size so I print it at 35-40% to make it doll sized. I used a dremel tool with a pointed end tool to create the hole in the end of it to attach the clear tube. I found this easier than trying to print the thin walls of the tube sticking out of the end.
