Coke Bottle Lid - With Siphon Tubes by titaniumfish Mar 27, 2013

Description

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)

Soo.. you're inclucing Thread_Library.scad - where did you get that from? I googled the name, and the first one I found ( github.com/syvwlch/Thingiverse-Projects/blob/master/Threaded%20Library/Thread_Library.scad ) 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...

Instructions

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.

<p>This is exactly what I was looking for to change my rear diffenrential oil.<br>Thank you</p>

<p>I sure hope you are using food grade CO2 and not an air compressor.</p>

<p>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 :)</p>
