Container Builder

Use the Container Builder above to create a 3D printed box STL (with or without a lid/lip) or a textured basket.
Export a ready-to-print STL or OBJ and follow these settings for strong, clean, support-smart prints.

Measure, Fit & Scaling

• Internal size: If your box must fit specific items, enter the item dimensions and add clearance (0.3–0.6 mm per side) in the app.
• Lid fit: For a lid with a retention lip, allow 0.2–0.4 mm radial clearance (total 0.4–0.8 mm) between lip and box wall.
• Scale in the app: Rebuild to the final size in the app. Scaling in the slicer can thin walls/lips and distort text or textures.

Orientation & Supports

• Box (no side text): Print open side up for a support-free interior and flat, strong base.
• Box with raised/engraved side text: Side text may introduce overhangs. Use supports touching build plate only with low density and add support blockers to keep interiors clean.
• Lid with lip: Print top surface down (on the bed) for the cleanest visible surface; enable elephant-foot compensation or use a light brim if adhesion is marginal.
• Basket option: Handles and certain textures will almost certainly need supports. Tree supports at low density work well; keep them off the interior with blockers.

When Your Slicer Asks to Repair

If your slicer prompts to repair the mesh, accept the recommended fix. Repairs close tiny gaps/non-manifold edges and typically improve printability without changing visible geometry.

Recommended Slicer Settings (FDM/FFF)

• Nozzle: 0.4 mm
• Layer Height: 0.16–0.20 mm (0.12 mm for showcase lids/text detail)
• Perimeters (Walls): 3–4 (≈1.2–1.6 mm) for sturdy boxes and lip strength
• Top/Bottom: 5–7 layers (≈1.0–1.4 mm total) for a smooth, rigid base and lid
• Infill: 15–30% (Grid/Gyroid). Heavier loads → closer to 25–30%.
• Speed: 45–60 mm/s. For crisp text/texture, slow external walls to 35–45 mm/s.
• Material: PLA for easy printing; PETG for durability/flex; ASA/ABS for heat resistance.

Print Settings — Quick Recipes

• Solid Box (no side text): 0.2 mm layers · 3 walls · 20% infill · Open side up · Supports: Off
• Box w/ Raised or Engraved Text: 0.16–0.2 mm · 3–4 walls · 20–25% · Open side up · Supports: On (plate only, low density, use blockers)
• Lid w/ Retention Lip: 0.16 mm · 3–4 walls · 15–20% · Top surface down · Supports: Usually Off (enable small supports if the lip overhangs are steep)
• Basket (handles/texture): 0.2 mm · 3 walls · 15–20% · Basket upright · Supports: Tree, low density (10–12%), interface on, blockers to keep interior clean

Support Tuning (when needed)

• Style: Tree supports (if available) reduce scarring on curved handles and textures.
• Density: 10–12% with an interface layer for easy removal.
• Overhang threshold: 50–60°. Raise slowly until bridges/overhangs look clean in preview.
• Blockers: Place support blockers to keep interiors and the lip channel free of supports.

Fit, Finish & Durability

• Enable elephant-foot compensation or slightly reduce first-layer line width to prevent tight lids.
• Lightly chamfer or sand lid edges/lip channel for smooth action.
• For load-bearing boxes, choose PETG, 4 walls, and 25–30% infill.
