I need a print-ready 3D model of a cartoon-style tree stump that will ultimately stand about six inches tall and function like a cup. The piece should be hollow all the way down, with a light-brown interior and a dark-brown exterior so it can be produced as a two-color print. The exterior bark must carry a moderate level of detail—noticeable grooves and patterns that feel lively without drifting into photo-realism. On one side, please “carve” my initials in a casual hand-drawn style so they look naturally etched into the wood. The logo goes on the underside, centered, sitting flush with the rim so the model still prints flat. Inside the cup, the base needs concentric growth rings to mimic a freshly cut trunk, plus a subtle wood texture on the inner walls so the light-brown filament has some visual interest. Deliverable: a watertight, manifold STL (or OBJ if you prefer) that slices cleanly at 0.2 mm layer height without supports, ready for two-color FDM printing. I’ll run final checks in PrusaSlicer, so please keep overhangs friendly and wall thickness no thinner than 2 mm.
