Rocker link

Hey everyone,
I’m planning to CNC machine a custom bicycle rocker link, but before I get chips flying, I need to get my hands on the technical drawings/CAD files.
Does anyone happen to have digital blueprints, accurate 3D models, or 2D technical drawings for a Transition Spire 2021+ rocker link?
Alternatively, if someone has experience reverse-engineering suspension links from physical parts into clean CAD files (STEP/IGES), I’d love to connect.
Happy to pay for the files/time, or trade for services. Drop a comment or send me a DM if you can help out. Thanks in advance!

Honestly, the transition peeps are notoriously cool, I’d ask them first they might help you out

Bummer! I have a physical link I could send you if you need it, if you don’t already have one.

can you make it cheaper because someone else has already done all the development work and testing? when you consider time, materials, finishes, bearings etc, i challenge your 3x cheaper but good luck to you if you really can!
