Designing a simple photo frame. I wanted to make it so that it prints without supports. While printing, however, the back support part wobbles/vibrates with movement, and is printing terribly.

Ender 3v3 CoreXZ, PolyTerra matte black filament, using the CR-PLA Matte profile in Creality Print 7. Tried printing at slow speeds, the issue still persists.

I’ve tried making the back support with only 45 degree angles (previously it was an x diagonal), made it thicker (from 0.75mm to 1.5mm). Nothing is working. Please find the stl and 3mf here (https://www.thingiverse.com/thing:7281179).

Is this a printer issue, a model issue, or a slicer issue? Please advise.

    I definitely want to get better, which is why I’m asking for feedback on the model as well. Please give me some tips and tricks to think and plan for efficient models that are best suited for 3d printing. How would you recommend I modify this model?

      Did you see I wrote that comment into a spoiler to shorten it in the post replies so it is not a wall of text? Sorry if my thoughts are hard to follow at times. I write in an abstract rough draft like format. I wrote several tips and how I approach a problem like this.
