Adjusting .stl file in Fusion 360

[wnchstrtnfldvlle]

I found this file on one of the filesharing platforms for 3D printing. My filaments arrive Friday and I'd like to start some printing, but I need to edit this first.

1. For those that are a lot better at this than I, how would I go about rotating the body of the holder to match the hypotenuse of the red triangle? I think I could just create a sketch plane along the bottom of the main body where it meets the gridfinity bottoms, then I believe there is a tool that would allow me to rotate the top portion along the axis to the desired degree of rotation. Does that sound like a decent strategy?

2. Can I just extrude along that same rotation to fill it back in?

Just looking for a nudge in the right direction so I can more accurately search YouTube for the right how-to's.

I just have the free version of Fusion 360 and I have not been able to modify an .stl file. I was just watching a YouTube about it last night. But I was unsuccessful at my first attempt.

Yeah, I just discovered how tough it can be. I was able to get to the point where you have to do a bunch of crazy edits. It would probably just be easier to reverse engineer the collet holders and design it myself, lol. Or I could just print it the way it is and save myself the hassle.

stl files are pretty ugly to edit. That being said if it is something simple, you can sometimes patch things up in the slicer itself, by adding material to fill holes, or negative volume to create holes. If there's a step file you might be able to modify it in CAD. I have done that, not in F360, but in FreeCAD. I would expect that some editing of a step file is possible in F360.

There is another option, I just modified a simple Cell Phone Tri-Pod mound with TinkerCad, it worked great for what I needed. I probably could have designed my own in Fusion easy enough but modifying it in TinkerCad was even easier.

Although I needed to go to YouTube to figure out how to use TimkerCad. In the end it was easy to use.
