Carrot top Aerogarden cover

Found something similar on Amazon, but it lets in light and allows mold and algae to grow. So I made one based off my simple cap design. This comes out to be about half the price, doesn't let in any light, and is universal (can fit Aerogarden, Ahopegarden, and Rainpoint systems). Plate sliced file included for tri-color. Can't seem to get the gcode uploaded, will update if I can.

Printed with supports for the overhang at the bottom of the plug. 

I made this in Tinkercad by stacking a bunch of objects together, and apparently this design isn't completely hollow. This is my first design and I'm going to try to refine. I'm totally open to any and all suggestions as well, and please feel free to remix!

Added a second version with a smaller carrot for faster printing, also looks little better in my opinion, and it still blocks light. I'm not happy with the bottom supports because I prefer little to no post production processing, so work in progress!
