Here's a project I've been working on for about 3 weeks now (on and off).
I'm not very good at keep plants alive, I'm hoping this helps somehow... probably not unfortunately!
All lithophanes were printed with Solutech PLA filament (Aqua Blue, Lavender purple and Real Green). The framing was Hatchbox wood filament and the pot was PETG as I figured it'd hold up better with the heat of the LED's against it and the water/soil on the inside.
I used PhotoToMesh to generate a cone litho with two pictures and then used Meshmixer to plane cut it, I had to generate 2 copies with different min/max thickness's because of the contrast difference. I created the framing with Inventor.
The purple looks much cooler in person, my cheap phone camera is playing tricks with the colors and it looks almost too purple in the pic.

Once all the pieces were printed I used a combination of gel control super glue and hot glue to assemble and used a 12v adapter with some LED strip lights wrapped around the pot.

The top chain spreader file I ended up not having to use for this particular plant because it's pretty short, but if you have a tall/bushy plant the spreader will keep the chains/rope spread apart so the plant doesn't run into the chains.
