STL, OBJ, and STEP assets from independent designers — ready to import into Shapr3D for product design, jewelry, industrial modeling, and 3D printing. One payment, permanent commercial license.
Shapr3D is a professional parametric CAD modeling application built for iPad, Mac, and Windows. It uses a direct modeling approach powered by the Siemens Parasolid geometry kernel — the same engine behind SolidWorks and NX — which means its STEP exports are fully compatible with any professional CAD workflow, CNC machining, and injection molding design.
Unlike traditional parametric CAD software, Shapr3D runs entirely on an iPad with Apple Pencil support, making it popular with product designers, jewelry designers, industrial designers, and architects who want precision solid modeling without being tethered to a workstation. Its strength is clean, manufacturable geometry — not organic sculpting. Many designers import reference meshes from marketplaces to combine with their parametric work.
Import decorative STL elements — filigree patterns, stone settings, botanical forms, crest shapes — into Shapr3D as mesh bodies, then boolean-combine with precision-modeled bezels, bands, and shanks.
Import ergonomic grip shapes, organic handle curves, and human-factor reference meshes to design around. Parametric structure, organic feel — without hours of subdivision sculpting.
Standard hardware (screws, bolts, springs, bearings), connectors, hinges, and off-the-shelf parts — import as STL or STEP reference geometry to design enclosures and mounts that fit precisely.
Mouldings, column capitals, decorative panels, and façade ornaments. Import as STL to combine with clean parametric wall bodies and roof elements in Shapr3D architectural workflows.
Imports as a mesh body. Ideal for decorative elements and 3D-print-ready parts. Can be boolean-combined with parametric Shapr3D geometry.
Browse STL →Imports geometry with optional MTL material data. Good for reference models and decorative elements with basic colour information.
Browse OBJ →Preserves colour and material groupings. Good for multi-part models and coloured assets from slicer workflows and Bambu/Prusa ecosystems.
Browse 3MF →Imports as a B-rep solid — fully editable in Shapr3D. Ideal when you need to fillet edges, add features, or combine with parametric design. Not all marketplace models include STEP.
Browse STEP →Shapr3D handles imported mesh bodies well, but very high-polygon STLs can slow the modeling environment — especially on iPad. Here are recommended polygon budgets by use case:
| Use Case | Recommended Poly Count | Notes |
|---|---|---|
| Decorative surface element | Under 100k triangles | Medallions, filigree, panels — combine with Shapr3D booleans |
| Reference part / hardware | Under 200k triangles | Screws, hinges, brackets — for fit and clearance checking |
| Organic form reference | Under 500k triangles | Ergonomic grips, handles, nature shapes — viewport stays smooth |
| High-res scan for print | Reduce before import | 1M+ tri scans can slow iPad — decimate in Meshmixer first |
Inspect every model in a browser 3D viewer — check topology, scale, and proportions before importing into Shapr3D. No surprise geometry.
One payment gives you a permanent commercial license. Use in manufactured products, client deliverables, and resold designs without subscription renewal.
Every download is invisibly watermarked. Creators can trace unauthorized redistribution — important for precision CAD files that have real engineering value.
Shapr3D can import STEP (.stp, .step), IGES (.igs, .iges), STL (.stl), OBJ (.obj), and 3MF (.3mf) files. For bringing in models from a marketplace like Proofly: STL is the most universally available format and imports cleanly as a solid/mesh body; OBJ imports geometry with basic material mapping; 3MF preserves color and material metadata from slicer workflows. STEP is ideal if you need to combine an imported part with parametric Shapr3D features — a STEP body imports as an editable B-rep solid, not just a mesh.
Shapr3D imports STL and OBJ as mesh bodies. You can position, mirror, and boolean-combine mesh bodies with parametric shapes, but you cannot directly edit mesh vertices in Shapr3D — it's a parametric B-rep modeler, not a polygon modeler. The workflow is: import the mesh as a reference or decorative element, then build your parametric design around it. For full editing, import a STEP file instead — if the model was originally created in a solid CAD tool and exported as STEP, Shapr3D imports it as a fully editable B-rep solid with filleting, chamfering, and feature editing available.
Shapr3D excels at precise parametric geometry but has limited organic modeling tools. The models most in demand for Shapr3D workflows are: decorative surface patterns and ornamental elements (medallions, filigree, embossed textures) that are hard to model parametrically; organic shapes for jewelry settings, character busts, or nature-inspired forms; ergonomic grip and handle forms for product design; mechanical reference parts like screws, hinges, brackets, and standard hardware; and architectural details like mouldings, corbels, and panel textures. Proofly has STL and OBJ files in all these categories from independent designers.
For STL and OBJ imports into Shapr3D, lower polygon counts import faster and perform better in the modeling environment. For decorative elements you'll use as surface overlays: under 50,000 triangles is ideal. For full reference parts: under 200,000 triangles. Very high-resolution scans (1M+ triangles) can slow Shapr3D significantly on iPad — consider decimating the mesh in Meshmixer or Blender before importing if you're working on an iPad Pro. For 3D printing workflows, the mesh resolution of the final STL matters more than the import mesh — Shapr3D exports its own clean STL at any resolution you need.
Yes. Proofly models include a permanent commercial license. You can incorporate them into products you design, manufacture, and sell — for example, a jewelry piece with a purchased ornamental STL detail, a consumer product with an imported ergonomic grip form, or architectural millwork from a purchased template. The license does not expire and doesn't require a subscription. The restriction is redistribution of the raw 3D files as standalone assets — using them as components within a larger designed product is fully permitted.
Absolutely. Shapr3D exports high-quality STEP, STL, OBJ, and 3MF files — all popular formats for marketplace buyers. If you design precision parts, product prototypes, jewelry, enclosures, or architectural elements in Shapr3D, you can export and sell them on Proofly. Proofly charges 0% seller commission — buyers pay a $1 platform fee, you keep 100% of your price. Every download is invisibly watermarked with HiddenMark so you can trace unauthorized redistribution.
