These are simple, stackable risers for tabletop RPG miniatures to show elevation. Note that although the renders make it look like the legs are different thickness, they are all 4mm thick legs (they just look skinnier on renders of a large or gargantuan base (2x2 or 4x4) versus a medium base (1x1)).

Printing: I recommend turning the objects on one side to print to reduce the number of supports needed.

Update 7/3/2021: I made the top square slightly larger to tighten the fit between stacked risers. If this fit is too tight for your 3d printer, you can use the openSCAD file or Thingiverse Customizer to create wider allowances by modifying the "fit_adj" setting.

I also added two risers that start with a 2x2in base and narrow to a 1x1in top (better for stability). Both of these are 2in tall, but in one the top is centered and in the other the top is in one of the corners. The openscad file does not generate these models -- they were created by modifying models in Blender

Update 7/8/2021: The SCAD file now also includes an option which you can enable to include bracers for the legs. They usually aren't needed, but they help connect the bottom legs more firmly and reduce the support material needed to print.
