Just click the part on to the doorstop, put strong tape on it, then firmly open the door.
Voilá! Your door will now remain open.

The Door Catch should work with any round door stop.
Just measure the diameter of your door stop and print the according file.
If you need a different diameter, just let me know and I'll add it!

Note: Remember to lift the door catch a bit when attaching it to the door to avoid it scratching on the floor.
