Why STRYX
Built like a product. Documented like a kit.
STRYX is more than STL drops—we ship the files, docs, community, and updates you need to actually finish the build.
Active builder Discord
Stuck on a wiring step? Want to show off a print? Trade mods and get answers from people building the same arm—not a dead support inbox.
Editable STEP files
Full STEP exports for major mechanical parts. Tweak tolerances, swap materials, or adapt mounting points in Fusion, SolidWorks, or Onshape.
Build guides, videos & docs
Photo-backed assembly steps, wiring diagrams, setup walkthroughs, and tuning notes—written for first-time arm builders, not just experienced machinists.
Full, up-to-date BOMs
Every screw, bearing, and driver with quantities, vendors, and alternates. BOMs update when the design changes so you're not chasing obsolete part numbers.
Regular platform updates
Firmware, documentation, and mechanical revisions keep shipping. Early supporters get file drops and changelog access as STRYX evolves.
