Window Frame Closing Bracket

cults3d

This thing is mounted on the inside of some windows and is used to close the window when turning the handle (see video). How I came to design this: After the mortar used to mount my window hardened the lower side of the window, along with part of the lower frame moved a tiny tiny bit down, causing the window closing mechanism to not catch all 3 of the brackets resulting in lopsided window. Unable to find a longer "bracket" or at least one without the window (they only come as sets) I decided to design my own. READ CAREFULLY FOR COMPATIBILITY: This design is for windows that have channel at least 4mm wide.
