This is a lithophane stand, designed as part of an wedding gift for a family member.
It uses the lithophane generator 3dp.rocks with the outer curve setting, but any (curved) lithophane with the following dimensions will work:
31mm high(when laying flat on table)
the design is made so that those values can be changed easily.
[Feb 12 2019] UPDATE:
Added a version without the rings.
I printed at 0.2, layers came out good. you can print at other resolutions, but i would not recommend going over 0.25mm.
For the top and bottom surface i used the Archimedean Chords setting in Slic3r. this goes well with the curve of the lithophane.
The only thing needed after printing are two M3x5 screws,
for tightening the Lithophane in the corners to prevent it from falling over.
I also put some dampening foam under the stand, the kind which often is put under chairs and couches.
I designed this in Solidworks 2018.
