Robert Herbst: I was able to fix most of my parts that had this issue by editing the SVG symbols in the graphic editor Inkscape. I noticed that objects(drawing) in the SVG start at x = -0.5px and y = -0.5px and it's bigger than the page by one pixel in width and height. Even vector coordinates never exited the page but all vector objects have a thickness of 1px and as a result a half pixel on the left, a half pixel on the right, a half pixel on the top, and a half pixel on the bottom.

So I selected all and moved it to the 0, 0 position and increased the page by 1 pixel in width and height.

You can find all SVGs bad and good for parts that I fixed here:

in case you need them for investigation.

Vasyl Skral: That's SUPER helpful information. Thanks!
