Lithophane Art lamp

EDIT: I had this posted on that other site and imported it here. This was originally created in July of 2019--------------------------------------------------------------------------------------------------------------I had successfully printed a couple lithophane lamps and bases but wanted to make a different lamp base. I fell in love with the art vase 3 created by Edmund Keefe and figured "Why not combine them and make a couple changes to the mechanism?"In addition to remixing the lamp, I wanted to add a little more stability and make it so the light socket and cord sets I bought off Amazon screwed directly into the top that supports the shade. My other goals were to need no supports and print easily. Oh, and in the spirit of full disclosure, I had never modeled anything before and had only been 3D printing for a few months.Should print fine without supports How I Designed This ===================Making the baseI downloaded the art_vase_3.stl and attempted to import it into Tinkercad
