Sub-Irrigated Planter (SIP) Continious Irrigation Block

Parametric Continuous Irrigation T-Block for Soda Bottle Sub Irrigated Planter (SIP) for use with container garden irrigation hose. Inspiration came from http://greenroofgrowers.blogspot.com/2008/07/lacinato-kale-in-recycled-pop-bottle.html & http://greenroofgrowers.blogspot.com/2008/07/how-make-two-bucket-sub-irrigated.html Instructions You can make self watering flower pots using a 2 liter soda bottle by cutting it in half at about 4 inches from the bottom & flipping the top over and placing it into the base. You can also stack two 5 gallon buckets for a larger SIP. This 'thing' allows you to connect multiple SIPs together enabling you to provide a water reservoir (such as a rain barrel)and have all of them maintain the proper water level easily. It's currently designed to use 1/4" OD container irrigation water line. Simply drill a hole in your SIP base and use a dab of silicone sealant between the T Block and the SIP base. The plastic nut is to hold it in place while the sealent cures. I printed mine out at .2mm layer height with 3 solid layers and 3 perimeters with a 10% infill. I wanted a good solid shell so it would be waterproof with a minimal plastic usage otherwise. [UPDATE] This is now parametric to allow you to change the size of the container it will attach to. Just key in the diameter of the planter. Soda Bottle = 100 ~ 4.5 inches 5 gallon bucket = 254 ~ 10 inches
