About this 3D model

Two connections parts for 100mm PVC air tube. One to connect the tube to the printers exhaust 120mm ventilator and another one to connect the tube to a second 120mm ventilator with an attached tube out of foil wich is then lead through the window. I Used an oven bag for this. The advantage is that it does not interfere with the window locking mechanism. The ventilator on the window side is mounted with some wire to the air duct.
