Thanks a lot, @spikeyxxx 😀!
I had to dissolve many edges at the green-blue part on the left side and bring the circular shape back to perfect circles with “Loop Tools”. The edges (marked with a more saturated yellow) are beveled. I duplicated one edge area and used it as snapping target for the resting three in order to get an even look.
At the magenta bolts holder, I made the edge loops run down straight from the holes to the axle bottom instead of directing them into the corners nearby because this caused a lot of edge stretching so that some faces were overlapping which was clearly visible.
The holding edges at the corners of prodtruding parts are always a challenge, escpecially when they run into curved surfaces. I have a mix of solutions which all aren’t 100 % perfect (I don’t know whether this is possible at all?) but some slight pinching is only visible if you come very close and I can at least live with it. Maybe you can have a look at it when I post my finished file?
