3D printed hydroponic system I modified, printed, and assembled.

Printed in PETG. Design available on Thingiverse. Instead of using only tubing, I used PVC for the part in the middle so it would stand up straight and not require tubing out the side and in through the top. I also am using a 6 quart clear Cambro container from Webstaurantstore instead of the Ikea ceramic white base in order to see water level. Planted with Tom yellow tomatoes, Buttercrunch lettuce, basil, mint, oregano, lavender and thyme.

First Face Shield Printed

Update: My build notes at NIH:




I used a custom cut mirror starting from 12×12 from Home Depot as the printing surface, and Simplify3d software to generate the gcode file, which set the nozzle to 210 and the bed to 60 on an Ender 3 Pro printer. Ask me if you need any help to replicate this. A second shield is printing now.
