Lithophane IKEA tea light shades

thingiverse

The LED candle gives a warm and cozy flickering light, just like a real flame. Easy to use, it comes with a built-in timer that automatically turns on the light at the same time every day and then shines for 6 hours. Shade tube: The tube needs an inner diameter of 76mm and top and bottom thicknesses of 3mm. Customizable Lithophane Shades: Using http://3dp.rocks/lithophane/ to create the lithophane STL. Mode: Outer Curve. Image settings: Positive mode, this makes pitch black thick (3mm) and pure white thin (.4mm). Rest is default. Model settings: Maximum Size: 240 Thickness: 3 Border: 0 Thinnest Layer: 0.4 Vectors Per Pixel: 4 Base/Stand Depth: 0 Curve: 360 The image height:width ratio I use is 4.3:1, but you can change it if you want a taller tube. Use a gradient to black in the image for a smooth transition to base and coupling. To connect multiple cylinders, simply glue them together with a coupling.
