Watch your attitude.

I think you still somehow assume this is some kind of ad to sell this design for money or I am a jerk for not just publishing it with source files.

Also not everybody spends their time designing and publishing whatever is popular at the moment on Makerworld to collect points/store credit. There is a different world that doesn’t run on Fusion360 source file most people could edit and can design parts with a particular material & print(farm)/process in mind to get the most out of the FFF 3D-printing process.
