About this 3D model

Lithophane lanterns, in the original size, the dimensions are 200mm x 200mm x 168mm (+ 80mm hatch). You need to create a lithophane image for embedding. Use the free tool https://3dp.rocks/lithophane/ in the image settings change to positive image and in the model settings change the image to 150 x 150 The lantern can be easily reduced and printed at any size reduction up to 50%. I use classic white PLA to print litophane images.
