Extender tube to add 5" of height to your Aerogarden Harvest.
The wire going to the LED lamp has enough slack in it to accept this, but it's tight so you may want to extend the wire as well. I've included the Fusion360 file so you can modify and add mounting holes if you like, but I found that it fits quite well on the bottom with just a friction fit, and for the top I just used the original screw and forced it into the plastic.
I printed using a Prusa i3 mk3s in PETG at 15% infill and it feels plenty strong.
I used "all supports" in PrusaSlicer, although it may be fine without the internal bridge supports because removing them was a bit of a pain.
