Paciefier: Both parts need to be glued together. ABS glue works great on PLA !

Notice: The pacifier was made for my wife who needed it for hosting baby showers! I don't feel I have to explain the fact that its not suitable for babies ... If you are this stupid you should NOT make babies in the first place.. also for the life of me I wouldnt understand how anyone this dumb can operate a 3D printer, but this is the internet and there are some pretty stupid people out there ;)
