Each lithophane panel is 108x78mm including 4mm border and 3mm
|

thickness. Do not forget to create positive images, not negative
|
||||
ones. You can use
|
||||
<link xlink:href="https://3dp.rocks/lithophane">3dp.rocks
|
||||
service</link> to create your own lithophane plates. The lantern can
|
||||
be printed with 5% infill but lithophane plates must be 100% infill
|
||||
and vertically printed. You can print several lithophanes at the
|
||||
same time with border on bed to avoid grip issues.
