The final land vehicle for the Delta Operation grand battlefield—the amphibious armored vehicle—has now been completed. With this, all land vehicles in the Delta Operation battlefield have been fully produced. Due to technical limitations, I was unable to implement a tracked chassis, so the tracked version, like the steel-pin version, is non-movable; however, the turret is designed to be fully articulated. After several rounds of tolerance testing, the filament used for printing was TPU PLA Basic, which ensures a perfect fit and smooth rotation of the turret. We hope everyone enjoys playing!
