I want to know if anyone has made a soda bottle cap with the threading. I would like help making the threads for a Pepsi bottle cap.
Look at this one: MOLDED THREADED CAP FOR PLASTIC BAG SPOUT
For proper dimensioning, data is available here: http://www.plasticbottle.com/techinfo/spi.html
An interesting detail on thread design bits: http://edibleintelligence.blogspot.com/2010/05/bottle-caps-2-electric-booga-dew.html
