I made two different versions, the screw version uses 5 m3x6 flat head screws (the same my switch uses), the snap fit version is made to just be snapped together. The snap fit version might be less tight depending on your printer and mostly permanent.
Print them in the orientation of the file, use “split into objects” in the slicer and print the two parts separatly in different colors. In the photo I used esun dark blue pla for the dark blue parts and landu/kingroon/deeplee light gray filament for light gray.
Don't use organic supports just use normal supports only on the front teeth section.
The author remixed this model.
Split in two parts and added two different attachment methods
