any 3D software for prototyping?

Hi guys I tried so many times to create my prototypes on Cinema4D but it’s a struggle to create everytime hinges, servos, screwes, actuators, etc etc.. . Is there some 3D software with all these mechanical components ready to use on your prototype? I already have the whole shell of it but I need to add all the mechanics now. Solidworks is for this purpose I guess (not sure) but I’m on Mac and I can’t afford such an expensive software, any alternative?
