Most saber-tooth skulls around are of the Smilodon so I saw the need to make this less common Machairodus cat.The jaw print as a whole and the cranium is 2-part designed to fit the bed of an ender3 S1 (22x22cm) already scaled to lifesize as a reference point if you want to scale it down.The jaw is free from the cranium and does not include a support to hold it with the mouth open like in the images

Minimum support necessary, in cura I use a support blocker for most of the model and use straight supports only at the bottom (see the last photo for reference).
