Lithophane cube, remixed from: https://www.printables.com/model/4492-customizable-lithophane-box-any-size (full credits to trv)
I modified this to allow for an LED Light to be placed through the middle - specifically I used https://a.aliexpress.com/_mNRxsEg (but it should be compatible with most LED lights like this, including the ones in the LED Light Kit from Bambu Lab.
Designed for 130x130 - I made my litho's from this site: Lithophane maker • Image to Lithophane software • ItsLitho
Settings I used were all default, except:
Nothing else adjusted
Printed using plain white PLA for the litho's.
