I was planning on making a quick cardboard case for before I work on my steel case. After I saw Punnet
I decided to make one, and use a similar design using a cereal box.
Planned it out on thin paper, then traced the design on cardboard.
It was a bit flimsy, so I glued on extra layers. The case feels very good for cardboard.
Final product. I'm thinking of spray painting it, though I'm not sure it's worth it.
