Star Destroyer model that holds a wing of 5 TIE fighters.
Plans are for 1/8" material, scale them to your material thickness. Cut out one of each file (.dxf or .svg) and follow stardestroyer_instructions.pdf to assemble.
This design is the "Imperial Class" that appeared in the original trilogy. There are many other, similar designs you could adapt this one to.
You could also change what fits inside. A deck of cards, shot glasses, or a Blockade Runner? Up to you. Lots of possibilities.
Message me if you want the CAD files.
