Large 220mm Lithophane on a base rotating at .6 RPM. The lithophane was generated at lithophanemaker.com and printed all white. I used a cheap set of watercolors to tint the ocean and land areas. The rotating base uses a small USB-powered, 59 RPM motor with a final gear ratio of 100:1. All stls are provided in the download section.
The base consists of five printed parts and some additional parts that can be purchased from Maker's Supply. See links in the Bill of Materials section below for the parts I used. I used part KA004 White LED Strip, but you could also use part KA001 RGB Strip if you want different color light. Total cost of parts is about $20-$25 depending on which LED strip you choose. Additionally, you will need four M3x10mm and one M3x16mm machine screws.

Printing Instructions
My profiles have all my preferred settings. Make sure to select your printer, plate and filament in Studio or the Handy App. If you prefer to plate them yourself or have a non-Bambu printer, the Earth lithophane is printed at .2mm layer height, 4 walls and 100% rectilinear infill. There are two height range modifiers set from 10-30mm and 214-250m with .1mm layer height. This reduces the chance of holes and gaps in the shallow-angle areas. I also added some small supports in areas with noticeable overhangs. The base and cover are printed at .2mm layer height and 5% infill. The gears should be printed at 25% infill. All parts can be printed in PLA.
