This is a 3/16″ thick steel laser cut 3D puzzle for a helicopter. The overall dimensions are 21″ by 17″ by 10″ tall. This is meant to be welded together for a permanent installation and can be painted or powdercoated or clearcoated very easily. They will ship in 3 plates, roughly 30 pieces total, that are easily punched out. Some slight modification via grinder or cutting disc may be necessary for a perfect fit, but assembly is typically 1-2 hours depending on skill level.
