IKEA Docent shelf bracket

I have an old IKEA DOCENT TV stand and shelves. most of the plastic shelf mounts went missing. As the TV stand is almost 20 years old, parts are near impossible to find. So, i took the one that i did have, and recreated it in fusion 360.

It'll fit tight in the shelf cutout with no sanding needed, just give it a little bang first to get it to set.
