Drain Pipe Herb Garden

So I live in one of those nosy neighborhoods and get subtle but constant hints from the neighbors for not having enough greenery on my terrace. I decided that I wanted to have something unique and a bit futuristic and designed these hanging herb planters. 

They attach easily using a combination of one cable tie and one cable tie head (that you just cut off of a second cable tie). You can use up to 3 cable ties as there is 3 slots for them on the left and right side. The little drains should be far enough away to not get any dirt on your drain pipe and still let the water drop into the below planter. This way you only have to water the upper planter (if you're really lazy ;-) ).

My drain pipe is 83mm in diameter, so resize accordingly. I made the planter a bit looser on purpose so it is easier to slide on and/or fit in a piece of double sided tape. 

I made a color change at 5mm to get the white “base”.

I really hope you like my design. Either way my neighbors are stunned and jealous.
