Dustbiters is a great game you can get it here: https://www.iam8bit.com/products/dustbiters

However one issue is that the cardboard insert does not accept sleeved cards at all. So I designed this small insert for my own collection.

Is nice and snug when the lid is closed and should be deep enough to accept thick sleeves. Rounded corners will reduce the amount of filament you use by a little bit.
