I made this model because a door blind hold down bracket on me and i didn't want to wait or leave the house to get new ones.

I made it 1mm thicker than the original model i went off of, hoping to increase it's strength.
I excluded the 2 holes on the other face for the same reason and because i dont need them for my application.

I printed with tree support but you should be fine printing without support.

Let me know if you have any troubles or if you'd like a revised version including all holes.

Thank you,
Peter
