Bugaboo stroller (Butterfly) bag mount

I have a friend who asked me if I could help him to replace a missing piece on his stroller for his kid.

I took a few measurements and did some free hand adjustments and got this piece together. Works great, so I hope it can come in handy for someone else.

I also added a piece without the pin for the bag, if someone would want to create something else. I've added the Blender-file here and STL's for both pieces.
