The Turkish news account @mechtechx shared a video showcasing a DIY solution in which a hole in a wall and a pipe connection, described as being 3D-printed, redirect cold air from a wall-mounted air conditioner into the room next door. The effect is demonstrated by a piece of paper moving at the air outlet on the other side of the wall. In the comments, many people pointed out that the installation appears to use ordinary PVC pipes rather than custom parts made with a 3D printer. While some praised the creativity of the idea, others argued that it is simply a basic ducting system adapted to distribute air. Several commenters also highlighted engineering limitations. Because the air conditioner's cooling capacity is now shared between two rooms, the unit would likely need to run longer, consume more electricity, cool both spaces less efficiently, and experience greater wear and tear over time.

A video shows a DIY solution for sharing air conditioning between two rooms using a pipe connected to a wall-mounted AC unit and drilled through the wall to an air vent in the adjacent room. A piece of paper demonstrates the airflow from the vent.
