for a Formula 1 Steering Wheel concept, i used a 3D Printer from the Velizy 3DEXPERIENCE Lab to print a first prototype to validate ergonomy of my concept : it's very useful to check overall proportion, accessibility of each command and buttons and wheels to make modification before a more detailed prototype. I recorded a first user test with gloves to capture issues on the model.

3D Ideation & Modeling made using CATIA Creative Design Experience application on R2025xFD01

thanks for your help @RS & @BF ! @SR
