To the blind, the outside of a 2L Diet Pepsi bottle, and a bottle of Lemonade look the same. There is nothing worse than a shandy made from beer and coke.
These re-usable labels clip around the neck of 2L PET bottles (Certainly the ones in UK and France), and contain brief labels to enable bottles to be distinguished from each other.
I printed with ABS, as it is more flexible than PLA.
Print this one upside-down. There should be no need for supports.
For me, on the Davinci Pro, the print takes around 40 minutes for one, and 4 hours for 9.
I made some of these with, and without vapour smoothing.
I found that it was better not to smooth in this case, as the braille is a lot clearer.
