Pull down shelf file

I am looking for a ffile for pull down shelving like this. Pull down shelf with plywood / woodworking / mechanism - Bing video does anyone have this or is selling this file?

It looks like his video has pretty clear cut list. im sure it wouldntbe hard at all to make adjustments to what you need.

several key dimentions are missing as well as what gas shocks he used and their lifting weight not tomention the other hardware so no It would not be easy.

the location of the holes is listed top to bottom but not front to back.
