Mitsubishi Delica L400 curtain replacement hook

My first go at 3D design.
My Mitsubishi Delica L400 came with nice stock curtains. Unfortunately, quite a few hooks were broken and the curtain didn't quite sit well on the window. Since I needed them quick, I just quickly designed a replacement.
Thickness is 2mm (close to original) but you can easily adjust it by changing the scale in Z axis.
