We decided to add a "headset" to our skulls.
We printed ours with .2 layer height and 10% infill. We did use a tree support at 25% threshold in order to only support the top handle. You may get some drooping on the handle if you don't use the support.
We have two versions - One has a bow and one does not have a bow. Each of these versions have a painted .3mf file.
