This is a custom lid for a coke bottle (tested with a 2 litre bottle). It has 2 siphon tubes at the top for your use.

I designed this thing as part of a drinks dispenser. One side of the siphon tube attaches to an air line. The other side has a tube that goes to the bottom of the bottle. Air goes in, liquid comes out (hopefully)


As im using a pressurised system to get the liquids out of the bottles, i needed this to be as air tight as possible. I've found the best settings as follows.

Infill: 100%
Shells: 2 (or 3 might be better)
Layer Height: 0.1mm (i've printed successfully at 0.2mm also)
Movement Speed: 80mm/s

Once i have the completed part i found using some plumbers tape around the thread of the bottle, helps it to become air tight. I'm pressurising bottles at around 5-7psi and this seems to be working fine.

This is a somewhat strange request, but do you by any chance have a model of a coke cap without the siphon tubes?

I think I'll take this and turn it into a rocket nozzle for a butane bottle rocket!

Soo.. you're inclucing Thread_Library.scad - where did you get that from? I googled the name, and the first one I found ( https://github.com/syvwlch/Thingiverse-Projects/blob/master/Threaded%20Library/Thread_Library.scadhttps://github.com/syvwlch/Thi... ) did not work with your scad-file..

The thread is the wrong way around in the OpenSCAD file - I had to mirror the file to get a right handed thread...

This is exactly what I was looking for to change my rear diffenrential oil.
Thank you

I sure hope you are using food grade CO2 and not an air compressor.

I'm using an air compressor to develop the system and make sure all the lines are plumbed properly and i have no leaks, but after that i'll be going to a "cleaner" food grade system :)
