Velux window holder

Meant to be used to hold a Velux window slightly open for airflow.

Amazingly my printer did not need supports for it but they are strongly recommended.

To install, place the bottom part first, then flex the top part just enough to get the locking slot into the hole. The window needs to be in the unlocked position for this to work.

The original file that seemed to be meant to prevent the window from opening more. In my case, given the angle of my window installation, my goal was to prevent it from closing. 

Changed hook to a slot and made it angled closer to the angle needed to align it with the window lock. Also increased the length.
