Hello! Thank you for the post. You can use scraps of wood to make a box or you can use cardboard boxes. Unfortunately, the hardest part may be the light source as the temperature in the incubator should always be around 99 F degrees or around 37.2 C
Please review this web page (link below) for detailed incubator instructions. If you would like to brainstorm further...please feel free to email me direct at kwagner@illinois.edu
