2020 Skinny Surface Mount

Quick and dirty remix of ikishk's 2020 aluminum extrusion wall mount. I wanted to use this to mount a piece of extrusion between two legs of an Ikea Lack table, and the original was too wide.

Update: The original STL tolerances weren't great, so I updated the file with a slightly larger model. Current file was perfect for my 2020 extrusion, which measures in at about 19.85mm.
