Parametric Square Lithophane Frame Generator

I really like lithophanes and wanted a fast-printing, bare-bones frame for smaller square lithophanes. This parametric frame is customizable using the Bambu customizer or OpenSCAD. I usually use it for 120mm lithophanes or smaller since I get great light intensity with a single light strip around the inside edge. They print flat with no supports in less than two hours for the 120mm frame and reflector. Use any color or monochrome lithophane generator like Make My Lithophane, Lithophanemaker, PIX
