SSTO Spaceplane Design Printable Model 3D print model

A design for an SSTO (Single Stage To Orbit) spaceplane I came up with - it's only a theoretical concept but it is an actual calculated design for an actual rocketplane, not just a sci-fi design - powered by 28 small methane engines with a wingspan of 16 meters this lifting body design could lift about 3000 kilograms into low earth orbit or about 1000 kilograms into geostationary orbit while being fully reusable. The model is slightly modified from the aerodynamics model to be printable - it is still full scale but both the rudder fins and the engine bells have been thickened so they are still printable with a normal printer nozzle when scaled down the lower side geometry is purposely simple in order to make the heatshield easier to manufacture in one or few parts the wing area to weight ratio or wingload is kept extremely light to reduce reentry temperatures and the geometry has a high aerodynamic aoa range allowing it to both fly with a high aoa during the hot phase of reentry to reduce heatflow while also being able to fly at low aoa during the colder phase and final landing glideslopw in order to glide more efficiently and give it more crossrange
