Watering spike for pop bottles - Updated 5/20/17

This is a spike that you screw onto an empty pop bottle to keep your flowers and/or plants
watered while you're away or just in case you forget a lot.

UPDATE: version 2
I changed the thread profile and slightly adjusted the thread pitch and the fit is perfect.
The wife wanted a textured cap, so I knurled the base of the spike to make it easier to
screw on the bottle. Both versions; smooth and knurled are now available.

NEW UPDATE: In response to a request to "fine tune" the water release, I have uploaded 3
additional iterations. Each has fewer release holes so you can adjust the release.

As always, the Inventor .ipt files are included in case you wish to modify them.

I uploaded this design for your use and enjoyment. If I have designed something that you can use, please download, print, and have fun with it. I have had a few folks that wanted to send payment. While I appreciate that, no payment is requested, and I have not set up a payment link. If you would like to show appreciation, just drop a comment on the page. That would be great! Too few things in life are free these days, so enjoy! :)
