A tapered wastebasket with an all-over honeycomb lattice and a solid floor: light, airy and sized to fill a 256 mm print bed in one go.

What's included

• mesh_wastebasket_250mm.3mf: print-ready, 250 × 248 × 231 mm, mm units
• original/mesh_wastebasket_original.stl: the designer's high-resolution source (unit-less, see note)

Specs

• 4.19 M triangles, edge-manifold and watertight; two shells (floor disc embedded in the lattice)
• Cone flares ~15°, so walls print without supports

Print settings

• PLA/PETG, 0.2–0.28 mm layers, 3 walls, 15 % infill
• Sink 0.5 mm into the bed (or build-plate-only supports) so the floor starts on the plate
• Scale to 60–80 % for a desk-sized bin

Known issue (documented, not altered): the solid floor is a separate disc whose underside sits 0.45 mm above the bottom of the lattice ring at 250 mm. Lower the model 0.5 mm into the bed in your slicer (or add build-plate-only supports) so the floor starts on the plate. The source file is unit-less (0.82 units wide); the included 3MF is an exact ×304.9 scale to 250 mm.

Blender check (live Blender 5.2.1 session)

Checks: bmesh non-manifold/boundary edges, loose geometry, degenerate faces, face-winding consistency, signed volume (outward normals), shell count, bounding box in mm, overhang area (faces steeper than 45° from vertical, bed layer excluded), and BVH triangle-intersection tests for mating parts. Not yet physically test-printed.
