Thank you for making the OpenExo project open source, and congratulations on your being accepted by Science Robotics! I am a grade 1 postgraduate student from Fudan University, China, trying to reproduce the hip exoskeleton hardware and have downloaded the CAD files from the repository.

However, I noticed that the mechanical files appear to include mainly SolidWorks part and assembly files (.SLDPRT / .SLDASM). For manufacturing, especially CNC machining, I could not find complete STEP files, 2D manufacturing drawings, threaded-hole callouts, or assembly drawings.

Would it be possible to share the following files for the hip belt assembly and machined parts?

1. STEP/STP files for all CNC-machined and 3D-printed parts
2. 2D manufacturing drawings or PDF drawings for the aluminum CNC parts
3. Threaded-hole specifications, including thread size, hole depth, and tapping depth
4. Assembly drawings or exploded views for the hip belt assembly
5. Any recommended tolerances, materials, and post-processing notes

In particular, I am trying to manufacture the aluminum ab/adduction blocks and want to avoid mistakes in threaded holes, hole sizes, and mating dimensions.

OpenExo is my life-saver. Just as you mentioned in your paper, most people(even researchers) lack full-stack capacity of making an exoskeleton from scratch. I saw your team has 11 people, which is incredible and prosperous, but we only have 2, our instructor asked us to go full-stack, but we even do not major in mechanics! Anyway, I really appreciate your work and would be really, really grateful for any additional manufacturing files or guidance you can provide.

Best regards,
Gao Siming
