pine tree relief 3d model

Create a single solid pine tree relief for FDM 3D printing. FRONT: realistic pine tree with trunk, branches, pine needles and detailed bark, sculpted as a 3D raised relief. BACK: MUST BE COMPLETELY FLAT, SMOOTH AND PERFECTLY PLANAR, like a flat wall. The back must contain ZERO tree details, ZERO texture and ZERO protrusions. Imagine cutting the tree from a flat sheet: the rear surface remains one continuous flat plane. The tree must stand directly on this flat back during printing. No supports, no floating geometry, no hollow areas, no disconnected parts. Maximum relief depth 5–8 mm. Single watertight solid mesh.
