3D printed parts to make a screen accurate bottle as seen in The Last Jedi where Luke...uuhh... milks a sea cow and drinks the green milk. Print the ring with no support For the base, you can print it right side up and it will print faster but will need support on the outside which will mar the surface. I recommend printing it upside down as it is oriented in the provided file. It will take longer and will print a lot of support on the inside but the outside will be much smoother, which matters more in my opinion.
The model is 88mm outer diameter and 85mm inner diameter. You'll need to measure your own bottle and adjust the model prior to printing. Just give yourself .25mm clearance for a snug fit.
Just paint the neck black (or use black electrical, athletic, of gaffer tape), paint the cap silver to match, add a gray leather band (one end comes to a point) and gray webbing straps, snaps, rivets, and waxed twine and you're all set! The bottle I used is this one.
I got one with a black lid. you need to cut 8mm off the bottom of the cap to make it thin enough to match the prop and to reveal more of the bottle's neck. You also need to cut a hole in the cap to match the opening of the prop. The bottle comes with two caps so you can leave one intact.
