When I was horsing around on the bed with my dog, one of the plastic mounting brackets on my pull out bed broke. I couldn't find a replacement anywhere online, so had to find my own.
I wanted to make it in PETG to make it sturdier but my test pla piece has been holding up just fine!
I am not sure what sofa I have but the its been working great.
How to print:
The image has an older version with a miscalculation where the mounting hole is too far away, and its not hugging the metal frame. I made an updated version v2 when I saw that. I told myself I'll use the updated version when the current one breaks, but it hasn't yet so I am stuck with the v1 for now.
