Mostly got it built before this one piece wouldn’t keep the drawer in place - basically got stripped during the installation process. I went to take it out, and the darn thing ripped on me. Because it’s ribbed inside, the plastic bit won’t come out to replace it. Entire second drawer can’t be installed now. Going to try returning or getting a replacement piece. 

Looks nice otherwise but this mechanism isn’t the best way to make this last a long time.
