first layer issues

Also you could try heating the build plate to 60c.
It makes pla stick to blue tape much better.

Also change your settings to 2-3 layers and shells and 10% infill with the 'print every infill angle' box ticked.
I really like the tringular infill pattern. It's quick and strong in all directions

It'll print faster, use less plastic and be just as strong.

I've just made some super strong brackets that will need to take a lot of weight and also flex.
Used 5 layers and shells and 20% solid tringular infill.
The layers give rigidity and strength while the infill allows for flex and impact.

By using shells and layers and different infill settings you can produce a surprising number of different material effects.
