About this 3D model

This prints pretty easy. You are going to want supports under the chins and possibly on the sides of the crossbones, but other than that it's easy. It fit's the bottle I have at 18.3 inside diameter and 29.5 outside. The inner plug is around 17.5 slanted to 20 at the very top inside surface, so a bit adjustable. I can mold just about anything to the top of this, if you want to request one give me a shout. John MacLeodCAD Technician and Designer
