Model of a stove for a bath + a constructor to create a stove for your size and task.

In the archive, the furnace is converted to EditablePoly, as well as the elements of the constructor:
-2 variants of the furnace
-2 variant of the hearth
-2 fire option (wood / coal)
-dampers \ dampers
-accessories

For correct operation, the dimensions of the furnace body (bake_body) must be divisible by 260 in width and depth, and 75 in height.

Bricks can be made with the FloorGenerator modifier, or you can use a ready-made wall.

The base with the Symmetry modifier, which allows you to edit the dimensions in width and depth.

In the constructor, to create holes for the firebox, the CoronaDistance (VrayDistanceTex) map in the Opacity slot, materials Bricks 1,2 and Concrete_body is used, which allows you to move and resize the firebox without changing the geometry of the stove itself.
All furnaces in the model have containers for subtraction (subtract_combustor), when copying, you need to add the subtracted container to the node input list.

Stoves \ plugs \ dampers are made of splines with modifiers, which allows changing one spline to change all elements at the same time.
