A cute little monster head which will vomit the drink of your choice into your glass. It can be screwed on any regular plastic bottle. There is a extra cap that can be screwed in the mouth. The cap for closing the mouth is however not 100% tight, when you screwed it on solid and you put it upside down drops will slowly come out.
This a remix of one my Bottle Monsters which you can find here: http://www.thingiverse.com/thing:1016582
There is no Support required. The mouth screw caps should have high infill.
I don't know how food save any 3d printing plastics are but I can however ensure you that I have not died yet and I will let you know here If this changes. Though it goes without saying you should make sure that your 3d printing is clean so that there are no tiny bits that can break of which can easily be the case with a print that did not come out perfect.
You have the choice:
Monster.STL or Monster-Tongue.STL (has a tongue which leads the drink a little better)
ScrewCap.STL or ScrewCap-Vomit.STL (Vomit like looking cap)
For the eyes the Iris parts are optional (they need to be glued in), there is also a variation with more tolerance in case you need that. You have to put in the eyes with some force in any case though.
At best print the ScrewCap(s) with a lot of infill so they do not break while screwing them in hard.
