This is still a work in progress. I have already printed it but it still needs some tweaking, I wouldn't recommend printing this for now.
This is a pocket Connect Four game designed to fit inside an Altoids tin. I've also made a Battleship game that fits inside an Altoids container: https://www.thingiverse.com/thing:2769799
You'll need some glue to stick the top and bottom of the grid together. You'll also need to print as many discs as you can (and can fit inside the container), in two colours of course.
I recommend printing the bottom of the grid with supports. The side panels don't need support if you print them with the grooves pointing downwards (it's better to use zig zag pattern or lines instead of concentric).
The second render shows the cross-section of the altoids container with all the parts fitting inside.
If you printed this, please post a pic in the "Made" section and let me know if I should change anything. Have fun!
