Thule ProRide 591 identifier

Thule ProRide 591 car roof rack identifier. Simple click on mechanism. It is used to quickly pair the marked key with the rack. I printed each one in a different color. PLA works good - if you have enough colors PETG will be better choice. Compatible with Runchn ALU WIND and probably other copies of THULE. Ideal to match colors with key markers - https://makerworld.com/en/models/1452153-key-marker#profileId-1512950
