This is case for a raspberry pi Zero made to fit a SPAM can, 200g size, the small one.
I'm using it to run Pi Hole an adblocker that sits on your network and acts as the DNS server and refuses to serve you adverts.
The display shows how well its doing and is an OLED 128x32 . There is also a push button between the GPIO pins so that it can do a remote shutdown and a recovery if needed. Spam Key also added on the top for detail.
I printed this (luckily) without support, but depending on your printer you might want to add supports to baseplate.
Once you have your SPAM i suggest making a Reuben Spam sandwich. Fry the SPAM, add some Gruyere cheese, Sauerkraut, Dijon mustard and thousand island dressing. Pop it all under the grille and you have both a delicious snack and a Pi case.
