Big StrawGlass - Practical

cults3d

I love the novelty of the original Big StrawGlass (http://www.thingiverse.com/thing:375602), but it takes some lungs to draw some liquid goodness through all that straw. So, I've remixed it to provide a more "practical" spiral straw that still looks like the original, but easier to clean, quenches the thirst and provides a better drain at the bottom of the glass. In the picture above with two glasses, can you tell which one is the original?? hint (http://www.thingiverse.com/make:211826) Just so people don't complain, you should strongly consider using food-safe plastic. Since I can think of so many other things to worry about, I printed in ABS and even vapor-washed it cause I'm cRaZy like that. ** NOTE: ** If you plan to print in ABS so it holds up better in the dishwasher then vapor wash it. If you're unfamiliar with the process, Google is your friend. I don't have an elaborate setup, I simply have a big glass cookie jar I sit upside down on a glass pie pan with a piece of cardboard lining the inside I saturate with Acetone and let the item sit in for several hours until I see a nice sheen. Take it out and let it air dry for a day (which it will continue to smooth as the acetone evaporates out of the plastic). FOOD SAFETY So I commented it's basically at your own risk like anything else you print. However, the question has come up if there are resources, processes, plastics, etc.. that could help deam this "food safe". Little bit of research lend me to a couple articles about the subject: https://pinshape.com/blog/3d-printing-food-safe/ http://joes3dworkbench.blogspot.com/2015/07/food-safe-video.html What started this was discussion about XTC-3D not really being food-safe.
