Indeed, it does not look like an unified design solution.
I do not have now any techical reasons for a revision for these parts, but if this somehow happens I promise to improve it 
I believe that finger grease is the primary cause of bad 1st layer adhesion problems. It’s insidious stuff that you can’t see and tends to smear with IPA. Acetone will take it off, but it is hard on the surface. I use a heated Bambu textured plate for my PLA and PETG prints, and have never used any glue. I also have never cleaned the plate, but I religiously put on Nitride gloves before I touch the plate. I have over 500 hours on my P1S and only had one 1st layer adhesion failure.
I did have adhesion problems with the Bambu smooth plate. But when I used the smooth plate from my old Prusa, they went away. The Prusa plate is smaller, but it is large enough to cover all the leveling touch down points if properly positioned. Again no glue and bed heat is on.
But have you seen the parameter below the activation?
It seems you left “Max detour length” = 0, which means de-activated…
Yes, I have seen it. Imo it has to stay on “0”. It means I want a detour whatever is the cost. Being deactivated, the software does not compare the detour required to avoid crossing walls with a given value and decide one way or the other, it simply makes the detour!
After 4-5 iterations I managed to get a variant that seems stable and it is quite easy to handle.
@All - I apologize for the off-topic

Those clips look great! To be fair you probably only need the new clips for the spool spindles as they are really the only ones that need to be removed regularly. I also like the feet modifications.

Have you calibrated the filament? I have known filaments to be as little as 1.70mm and calibrated for that size. Then another color such as glow in the dark from the same brand may be closer to 1.75mm.
It dosent take much of a difference in diameter to cause over extrusion which will cause the nozzle to crash usually higher on the model.
Also 75c seems quite high for most PLAs

Also I use isopropyl alcohol pads and a good bit of manual friction to clean my beds and never have any adhesion issues. Of course I am anal about never touching the beds and I always wash my hands first.
