1:35 Ventilation shaft 10x20mm expansion

An expansion for a 10x20 mm ventilation shaft in 1:35 scale

The item 1:35 Ventilation shaft 10x20mm expansion from RT-Diorama is a scenic accessory for a diorama, not a model of a vehicle or a building. It relates to ventilation ductwork of rectangular 10x20 mm cross-section, which in 1:35 scale corresponds to roughly 35 x 70 cm of real profile. The expansion marking in the name refers to an extension of ductwork of the same size; whether it is a usable whole in its own right or an accessory that follows on from the basic version does not follow unambiguously from the name.

Why a longer run changes the result

A flat rectangular profile runs along a wall excellently and follows the architecture, so a long run can be built from it that passes through the scene from one edge to the other. It is exactly a continuous run that turns a diorama into a setting: the viewer works out where the air comes from and where it is going, and the scene stops looking like a collected heap of details. The expansion version is therefore the answer for scenes where one length of ductwork simply is not enough.

Tips for placing it in the scene

• Lay the run out dry over its whole length first and only then deal with the details.
• Keep the ductwork a constant distance from the wall; a varying distance shows at once.
• Put the bends and the branches where a penetration or a machine justifies them in the action.
• A long run above the heads of the figures helps to frame the scene and to hide the edge of the board.

Who the set is for

For modelers who create a more extensive factory or city scene in 1:35 scale and want to tie it together with continuous technical infrastructure. It also suits completing a scene built earlier where the ductwork ends too soon.
