I was asked to make this  for someone, and im not quite sure what it was for but they called it a interlocking T and it was for some shelves, so i thought well i dont know if this exists yet so i thought i upload it.

If you happen to know what it is leaving a link to the product or letting us know would be great!

For this print it is just a copy in the shape of the bowtie looking plug there that is normally injection modeled.
