What file formats does MakerSuite 3D support?

MakerSuite 3D supports KiCad (.kicad_pcb), Gerber (RS-274X .zip/.gbr), Eagle (.brd), EasyEDA (.json), and Altium (.PcbDoc) files.

Is MakerSuite 3D free to use?

Yes, MakerSuite 3D is completely free. No signup, no installation, and no file upload limits.

Are my PCB files uploaded to a server?

No. All file parsing happens entirely in your browser. Your files never leave your device.

Does it support 3D component models?

Yes. Over 116 realistic STEP 3D models are loaded from CDN, and you can upload custom STEP files for missing parts.

Can I export the Bill of Materials?

Yes. You can export BOM as CSV or TSV, with LCSC, DigiKey, and Mouser supplier columns included.

Can I compare BOM prices across suppliers?

Yes. MakerSuite 3D searches LCSC, DigiKey, and Mouser for real-time pricing and stock. You can compare unit prices, MOQ, and availability across all three suppliers side by side.

3D STEP Model Viewer for PCB Components

April 4, 2026 3D STEP models rendered on a PCB board

Realistic 3D Components on Your PCB

MakerSuite 3D loads real STEP 3D models for your PCB components, replacing simple boxes with photorealistic shapes that match the actual parts on your board.

How STEP Model Loading Works

When you load a PCB file, MakerSuite 3D matches each component's footprint to our library of 116+ STEP models hosted on a Cloudflare R2 CDN. Models are loaded progressively — components closest to the camera load first.

Component Library Coverage

Resistors — 0402, 0603, 0805, 1206, 1210, 2512 packages
Capacitors — MLCC, electrolytic, tantalum in common sizes
ICs — QFN, QFP, LQFP, TSSOP, SOT-23, SOT-223, SOIC packages
Connectors — USB-C, USB Micro-B, pin headers, JST
Passives — inductors, diodes, LEDs, crystals, switches
Modules — ESP32-WROOM, popular development board components

Custom STEP Model Upload

Missing a component? Upload your own STEP (.step/.stp) or STL files directly in the detail panel. Custom models are saved to your browser's IndexedDB and persist across sessions.

Performance Optimization

Priority queue — camera-nearest components load first
CDN delivery — models cached globally via Cloudflare R2
IndexedDB cache — downloaded models are stored locally
Fallback boxes — components show placeholder geometry while loading

Frequently Asked Questions

How many 3D STEP models are available?

Over 116 component models are available via Cloudflare R2 CDN, covering resistors, capacitors, ICs, connectors, modules, and more.

Can I upload custom STEP models?

Yes. You can upload your own .step or .stp files and they'll be cached in IndexedDB for instant loading on future visits.

How are components matched to 3D models?

An IPC-7351 footprint matcher combined with manufacturer MPN lookup automatically finds the correct 3D model with up to 97.8% match rate.

What happens if a 3D model isn't available?

A proportionally-sized fallback box is rendered based on the component's pad dimensions, so you still see accurate board layout.
