A straw to enjoy your bubble tea. I've made a vase version but it's not been printed at this time. I also suspect a vase print would need post processing.
I may add more of a spike on the tip if i find this model is lacking puncture power.
I've placed the print in this orientation as it seems to create the safest straw. If the unfinished rings of the print are at the bottom of the cup they could snap off and be sucked up the straw. Ouch! As it is now, the delicate part of the straw will be at the mouth so if the straw is damaged the user will know immediately.
As for chemical safety, it's down to the filament you use. I do not know what, if any filament is safe to sue.
The raft and support setting are up to you and your printer. I'm using a glass bed and Elmer's disappearing purple glue stick and need neither.
Be sure to clean and oil your Z lead screws to get your best straws.
The brand and material cannon't be recommended as I don't know what if any material is safe.
