Designed for the leviathan mission deck sleeved with Ultra-Pro 70mmx120mm sleeves although should work with other sleeves.
Holds the cards in the order: Rules Guide, Deployment, Mission Rules, Primary Mission, Attacker Secondaries, Defender Secondaries, Attacker Gambits, Defender Gambits.
To keep it light I printed using only 1 wall, 8% gyroid infill, 2 top layers, 2 bottom layers. That should keep it to around 160 grams of filament and the strength is adequate. Gyroid infill with one wall added an mottled pattern to mine which I think looks interesting.
The author marked this model as their own original creation.
