About this 3D model

This is a design I made up a few years ago that i've made 2 diferent ways. One is a layered version that can be printed with or without ams. To print it without AMS you'd need to pause at certain layer heights and change the filament. For printers with AMS you can print either way if you want it smooth/flat or layered for an extruded layered look. The one labeled smooth should be printed face down, the one labeled layered should be printed face up, the file with 1 of 4 and so on should be printed face up as well.
