Reddit user Luke_Matthews makes some amazing chipboard boxes for his cards games. Not only that, but he detailed the process of making said boxes around 4 months ago in this reddit thread. It’s certainly more than I could handle, not being crafty at all myself.
Luke’s primary reason for making these boxes was to better organize his shelves. Frustrated by the fact that publishers don’t adhere to any strict box sizes for games, he set out to great his own that would be more uniform, easy to store, and easy to find on the shelf. A lot of these games come in boxes with an odd footprint, a tin, or have a box that can’t support the cards if they’re sleeved.
The outcome of his efforts is pictured below.
