I created a panda head that will fit on the dummy 13 model below.  https://www.printables.com/model/981111-dummy-13-version-10 

I printed this with PLA, 0.2mm and no supports but with a full brim on an Elegoo Neptune 4 Pro. 

Once printed you will need to pull the brim off the hole in the bottom and then just insert the frame, head.stl piece from the dummy 13 model and you are good to go. That piece can be found at the below link.
