I dediced to build a wooden box for the fan. Originally I wanted to build a cube, ad a connection for a duct to it and place the box out of the house.

It turned out that the ductwork would be far too complicated and pricy for one use of the entire box, so I just left out the rear wall and decided to place the box on two sawbucks in front of the window.

I used 16mm MDF for the box. The inside of the box is 50 x 50 x 50 cm, so I needed

• 1 plate 53.2 x 53.2 cm
• 2 plates 53.2 x 50 cm
• 3 plates 50 x 50 cm

The plated were assembled using my freshly bought biscuit joiner and Ponal Express glue (which is the de facto standard wood glue among amateurs in Germany).
