3D STL Viewer : Smart Split

Take full control of your 3D printing workflow with the ultimate all-in-one 3D utility! Designed specifically for 3D printing enthusiasts, makers, engineers, and hobbyists, this app lets you inspect, prepare, and optimize your 3D models directly from your mobile device.

​Whether you need to fit oversized models onto your printer bed, calculate precise printing costs, or convert CAD files on the go, our powerful toolset has you covered.

​🌟 KEY FEATURES

​✂️ Precision Model Splitting (STL Slicer & Cutter)

​Cut & Split Large Models: Easily divide oversized STL files into printable parts with our interactive cutting plane.

​Smart Connectors: Add aligned alignment pins/dowels and snap-fit joints so your sliced parts assemble seamlessly after printing.

​Export Individual Parts: Save cut components directly to your device storage ready for your favorite slicer (Bambu Studio, Cura, PrusaSlicer).

​💰 Advanced Filament & Print Cost Calculator

​Accurate Material Estimation: Calculate total filament weight (grams), filament length (meters), and print duration based on your exact infill, wall count, and layer height.

​Detailed Cost Breakdown: Factor in spool price, electricity consumption (kWh), machine depreciation, operator labor rates, failure waste allowances, and taxes.

​Support & Density Analysis: Estimate extra support volume and material overhead for both FDM and Resin (SLA) prints.

​📐 Professional Proportional Resizing

​Exact Dimension Scaling: Scale your 3D models with millimeter-level precision across X, Y, and Z axes.

​Maintain Proportions: Scale uniformly or customize individual dimensions without losing geometry details.

​Direct Export: Save your resized 3D models instantly as watertight STL files.

​👁️ Fast & Smooth 3D STL Viewer

​High-Performance Rendering: Smoothly inspect STL, OBJ, GLB, and GLTF files with touch gestures (pan, zoom, rotate).

​Custom Appearance: Change model colors, surface roughness, metallic finishes, and lighting angles to preview prints under real-world conditions.

​3D Overhang & Support Preview: Identify steep angles and potential support-heavy zones before sending files to print.

​🔄 Universal 3D File Converter

​Lossless Format Conversion: Convert between STL, OBJ, GLB, and GLTF formats in seconds.

​Ready for 3D Printing: Ensure converted models are clean, manifold, and ready for slicing.

​🚀 WHY YOU NEED THIS APP

​Save Failed Prints: Avoid running out of filament mid-print with accurate weight and cost calculations.

​Print Beyond Build Volumes: Overcome bed size limits by splitting large sculptures, cosplay armor, and functional parts with built-in connectors.

​Mobile Convenience: No need to open heavy desktop software just to inspect dimensions, split a part, or estimate a print price for your clients.
