I wanted each mount to perfectly fit the screw holes where the legs used to be mounted on my Walmart 55" Sceptre UHD/4k TV (U550CV-U).

I also needed to modify the square opening of the mounts to perfectly fit my Klipsch Cinema 400 soundbar.

After two test prints - this was the final product. The front of the mount lines up with the front of the TV, and no extra space between mounting bracket and holder.

I used PLA with 10% infill. Works great.
