sorry wrong pic.

I'm not experienced in either of these, but here's my thoughts: NURBS might help you on the modelling side, but eventually the 3D printing software will probably convert it to a mesh of polygons anyway.

anyone know how to make shape in this pic? should be quite easy?

Try manipulating vertices on a subdivided cube with propotional editing enabled

1, make cube, go into edit mode, select all edges (key "A" on the keyboard) and make the "mean crease" 1 on all of them. When you make a full(1) mean crease on the edges its wont be subdivided/smoothed there on this edge.

2, make loop cuts like a parcel.

3, mush vertical loopcut ontop down and cut horizontal up

4; to get a smooth shape you apply subsurf modifier

could also do that by starting with just a plane, then duplicate, extrude, and evenly scale the outermost edge loop to get the cube.

You probably can make it a bunch of different ways, maybe even try boolean, but I just thought this was the easiest way for OP to replicate because it doesnt have that much work stepts and should be doable by someone with little expirience.

enable this add-on that lets you make meshes from math functions. all that's left to do is to extrude/scale the outer loop to make a cube.
