ThinkFun soda bottle connector

My entry to the ThinkFun challenge, this part allows you to connect your projects to a soda bottle.

I build this around the standard 28mm bottle cap compatible with most common soft drinks small, medium and large bottles.

You could fill a bottle with water or sand and use it as a weighted stand, you could use the smaller sized bottles as extra chunky - go anywhere wheels, or you could add bottles as floats or pontoons and make your projects amphibious!

I looked at several connection options but in the end decided that simply adding a 1inch rod to the cap made the most sense and was the easiest to print and use.

The model prints really well with no support and no raft, it came off the build platform with a little tap.

I could not find an exact measurement for the rod, but I settled on 7.4mm (easily adjusted).

Enjoy!
