If anything I learnt in a few years of 3d printing and design - is parametrization and simplification.
Previous stand required multiple parts, mirroring, screws.

This one-part approach achieves the same thing - a solid stand that can be adjusted to lift up your Feit grow-light.

The best part, is when you don't need the grow-light - these are stackable containers, with a small pour guide/channel.

For a snap-fit to Feit grow-light, scale it down 1-2%.

Printed in vase mode, with 0.9mm height on a 1.2mm nozzle with 2mm wall thickness. Print time was 37 minutes. These snap well into each other.
