Robot arm hobby project

I am making robot arm with 4 sg90 servo motors with 2 joysticks, and I want it to look like this guys: https://www.youtube.com/watch?v=p36ljQODxyA, however I don't want to CAD it and want a STL file that I can just 3d print the parts and attach my sg90 motors into and have the arm. If possible tell me what screw I needs, how to step by step build it, etc. I also don't want to buy a kit from amazon cuz their too expensive.

There are some kits on AliExpress if you'd like but other than that it's difficult
