01 — What’s included

Every File
You Need

One purchase, everything required to print and assemble a complete 6-axis robotic arm on your own 3D printer.

Fusion 360 Assembly

Full parametric assembly file. Every component, joint and constraint included. Modify dimensions, add custom tools, or redesign parts entirely.

.f3d Fully parametric All joints constrained

STL Files

Print-ready STL for every individual part of the arm. Compatible with any slicer — Cura, PrusaSlicer, Bambu Studio, OrcaSlicer. Optimized for FDM printing.

.stl All parts separate FDM optimized

3MF — Pre-Oriented

Bambu Lab and multi-material printer ready. Parts pre-oriented for optimal print quality with support structures already configured. One-click print.

.3mf Bambu Lab Pre-oriented

STEP Assembly

Universal format compatible with SolidWorks, CATIA, Inventor, FreeCAD and any professional CAD software. Perfect for engineering workflows and custom modifications.

03 — Why these files

Built for
Makers

Designed by engineers who actually built and use the arm. Not a concept model — a working robot.

01

Minimum 200×200mm Print Bed

Every part fits a standard Ender 3, Prusa MK3, or Bambu Lab printer. No industrial printer needed. ABS, PETG or ASA recommended for structural parts.

02

Parametric & Modifiable

The Fusion 360 file is fully parametric. Adjust link lengths, add end effectors, mount cameras or custom grippers. The arm is your canvas.

03

Works with Arctos Studio Software

Pair the printed arm with Arctos Studio Pro for AI control, ROS2 integration, computer vision, PLC programming and reinforcement learning experiments.

04

Active Community & Support

Join 2,000+ builders on Discord. Get help, share mods, and access a growing library of community-made modifications and upgrades.

05

All Future Updates Included

One purchase, lifetime access. When the arm design improves — better joints, new gripper designs, v3 hardware — you get the files automatically.

05 — Questions

FAQ

Any printer with a minimum 200×200mm build plate works. Common printers used by our community include the Bambu Lab X1/P1, Prusa MK4, Creality Ender 3 and Voron. We recommend ABS, PETG or ASA for structural parts — PLA is fine for testing but lacks heat resistance for continuous use.
Absolutely. The Fusion 360 file is fully parametric — you can change link lengths, add custom mount points, design your own end effectors or modify any component. The STEP file lets you import into any professional CAD tool. The only restriction is commercial resale of the files themselves.
The CAD files are the design only — you’ll also need motors, bearings, belts, electronics and fasteners to complete the build. Check the full Bill of Materials at arctosrobotics.com/bom/ for a complete parts list. We also sell pre-sourced hardware kits if you want everything in one order.
Immediately after purchase you’ll receive an email with a download link for a ZIP file containing all formats: Fusion 360 .f3d, individual STL files for every part, 3MF pre-oriented files for Bambu Lab printers, and the full STEP assembly. When updates are released, you’ll receive a new download link automatically.
Autodesk Fusion 360 — available free for personal/hobbyist use. If you prefer a different CAD environment, use the STEP file which opens in SolidWorks, FreeCAD, Inventor, CATIA and any other professional CAD application.
