As a child in the 80s, I remember scraping ice off car windows with a broken cassette tape case. This model is a throwback to that era, modeling the general shape of a cassette case half. A silhouette design of a cassette B-side covers the front.
It actually works quite well. The long edge makes it efficient and flexes along the curvature of the car window. The grip makes it easy to hold and pick up with gloves on.
The author marked this model as their own original creation.
