Hydroponics tower

This is a model I came up with which is simpler than most of the other options our there. The segments are infinitely stackable. The base has 3x .25" mounting points. The lid has a ½" spigot for a flexible tube to be hooked up to along with your water pump. The basket holes are sized to fit a 2" plastic mesh basket. Each segment including the base has 3 holes for plants. I plan to keep them rotated in the staggered fashion as shown to give each root system the most space. The model does not include the mesh baskets, they are in the picture but need to be purchased separately. 

Base v3 has a larger mounting flange which should make it more durable and rigid however it uses much more filament and adds about an hour to the print time. otherwise it is identical. 

Edit: After using the tower for a few months I modified the cap/ shower head section to improve the water getting into the mesh baskets and to help keep the hose on. Unfortunately the changes will make it a more difficult print however it should work much better. The most up to date version of the cap is V4.
