These files are visually quite accurate to an original 5L Trinkwasser bottle, however, I have only every printed one prototype and did not refine the file further so I do not consider the file to be truly a finished product. That being said, the file was able to create the bottle in the picture which is actually pretty decent. It is likely that you would be able to make a working bottle based on this file simply by playing with your wall settings etc... Mind the bottom corners, they overhang enough to cause some sagging depending on your printer and settings. I would recommend printing in PLA or PETG and possibly lining it with some food grade epoxy when finished. The hardware can be made from a metal coat hanger working from pictures, I have done it before, its not difficult at all.
There are 3 STL files included which are in a .zip folder. (I have to do it as a zip because its the only way for me to send multiple files with this set up).
1 for the lid
1 for a bottle with a handle
1 for a bottle without a handle.
