I recommend to print 'Body' in PETG - in the car PLA might deform during summer heat. Print-settings for ‘Body’ are not critical - I even used 0.6mm HF nozzle with 0.32mm layers and variable layer hight in Prusaslicer and the outcome was acceptable.
Pad1 + Pad2 are optional. Use flexible material like TPU. Use thin layers like 0.15mm as TPU otherwise might have issues with the overhangs.
If you own a Prusa XL use the multimaterial version to print as a single object (MMU is not sufficient as it does not support flexible filaments)
