This is a handmade attempt at recreating the tank from Atari's 3D vector graphics classic BattleZone. I never played it in arcades, but it was an included game back on my parents Windows 95 computer. I recreated it for a BattleZone clone HTML5 game I am working on.
I printed it in glow in the dark filament. But it would be really cool to redesign the model to be printed with dual extruder: glow in the dark for the exterior lines, and black for the fill to really look like the tank from BattleZone.
You'll definitely need to scale it up in your slicer.
You will need supports to hold the turret up. Also scale it up in your slicer about 3000% or so. The original model was normalized to 1 for convenient use in making a videogame, but that means your slicer thinks its less than 1mm in length.
