Big StrawGlass - Practical

thingiverse

I love the novelty of the original Big StrawGlass, 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? 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. 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 deem 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 it all was my test print of straw-glass-practical-v4-beta.stl in ABS at 20% infill and 3 top/bottom/outer layers still leaks unless I vapor wash it in order to chemically seal the imperfect layer adhesion of ABS. I have a new "high-res" version of v4 I'm printing in PLA to see if maybe ABS isn't the right stuff unless you intend to vapor wash it. I'm updating some of the details above with my findings. straw-glass-practical-v3-beta.stl is the next iteration of improving the straw and fixing the weird mid-section. I married the new straw and glass in Meshmixer and imported into Tinkercad where it translated the stl by making the entire glass solid. While in Tinkercad, I hollowed the straw. Returning the final model into Meshmixer to correct any fragments and I smoothed the inside of the straw at the top. Sooo, I would definitely not print 100% infill. straw-glass-practical-v2-beta.stl is an updated version with a cleaner insides of the straw (most attention to the top) and a larger bowl at the bottom. I haven't printed it, yet, so I'm listing this as beta. Looking at the original, what I thought was filled by me is actually flawed to start with, the mid-section is actually solid. Once I get one printed and tested (I won't vapor wash it) to see if there's any leaking - I'm thinking of printing in 20-50% infill (haven't decided) and see what happens. Tinkercad doesn't translate the original properly, while it doesn't matter on my remix, it is interesting to discover.
