Fortified Watchtower RUIN — 28mm / 1:56 Tabletop Terrain, blown-open brick shell

Generated — and then destroyed — with PrintHaus

This is the same tower as my Fortified Watchtower, generated in my browser with PrintHaus, the parametric CAD generator for 3D-printable buildings that I develop — then hit with the app's Bomb Blast tool. It is not an AI model: the blast is a real geometric operation on real solid geometry.

A shell tears a crater through the building, walls and roof break open with jagged edges, and anything that loses its support falls away by itself. Here the blast took the hip roof and the wrap-around balcony completely and blew the upper floor open, so the interior staircase and rooms are exposed.

That is what a generator gives you that a fixed STL cannot: one building, any state you want — intact, half-wrecked or a burnt-out shell, and you decide where the shell lands.

The model

A ruined version of the two-storey brick watchtower: a direct hit has torn the roof away and gutted the upper floor, leaving a roofless, battle-scarred shell for tabletop battles, skirmish games and dioramas. The brickwork on the walls is real printed relief, modelled into the geometry, not a printed-on image. Windows have sills and muntins and print without glazing.

Printing

Scale 1:56 (28 mm) — approx. 117 × 117 mm footprint, 100 mm tall. 8 parts, supplied both as 4 ready-to-slice Bambu Studio plates (.3mf) and as individual .stl parts converted 1:1 from those same plates — identical geometry, so any slicer works. 0.2 mm layer, 2 walls, 12 % infill, approx. 6.6 h and about 117 g PLA. Parts are pre-oriented flat, no supports needed. The colours are just my filament choices — swap freely.

Print it alongside the intact tower for a before/after pair.
