This is a cheap IKEA lamp hack that requires a large printer (~200mm). Using this $5 lamp and these $3 lights http://www.ikea.com/us/en/catalog/products/20055421/ http://www.ikea.com/us/en/catalog/products/70326571/ I was able to create nice lithophane lamps for my friends and family.

First off you will need to create the shade, go to this website

upload a few pictures, choose your resolution and thickness. I stuck with .75 base thickness, smoothing 5, 1.0 font thickness (didnt end up having any text) with an Inner radius of 94 (188 Diameter all together so your printer must be at least 190-200mm in Diameter).

Then for the top, I provided a plain top (187mm in diameter), how ever if you customize it using some Lithophane prints, make yours here

and here is the top on tinkercad

then resize them using tinkercad and or 3Dbuilder (default windows app) I took this top and just placed the lithophanes on top and grouped them together then printed them out using cura.
