AC Vent Tube Riser

A Riser used to prop the vent tube holder above the window frame, this way you can still lower your blinds and keep the heat out. No more need for crushing the pipe or finding towels to manage the area around the tube. Designed to be sturdy and interlocking with itself, so you can print multiple to fit the width of your window. The slot for the tube holder is 17.2mm and the height approx 13cm. Tried to optimize the shape to use a minimum in filament, but still keep a solid surface in the inside to block airflow from outside. Print in heat resistant filament. My example is done in ABS.
