Door stop for Schuco Corona CT 70

Disclaimer: 

This model may totally NOT work in your situation. My model is made for my door on my house. 

The way my model works could be an idea for you. Perhaps my model fits, perhaps it requires some changes by your hands.

I have Schüco doors and windows. But one thing stays a problem: keeping open the kitchen door. My wife placed a bucket against the door to prevent it from closing but that leaves scratches on the door. 

The door has a profile with a groove of 12mm on the underside. My guess was I could use it to insert a thing to prevent the door from moving. First I created a rotating stick which rotates into and out of the groove. But handling was drama.

Then I thought about using magnets. So this contraption was created.

How it works:

When opening the door to the point where it should stay open,  the door hits the door stop. The door stop tilt upward. Then a bunch of magnets in the door stop get closer to a bunch of magnets I put into the groove at the bottom of the door. From that point, the magnets attract enough to pull up the door stop even further. With that movement 2 wigs also enter the groove, preventing the door from moving.

The blue part is the door. Inside is on the left, outside on the right. Magnets in the groove are not in the drawings.

To unable the door stop, just step onto the tab. The door stop tilts down, the wigs get out of the groove, the magnets move apart enough to stop attracting one another so the door can be closed again.

Door stop is printed in 2 materials: TPU for the door step, so it is somewhat flexible. The hook part is made from PETG

Extra needed:

• 4 round magnets. 10mm diameter, 10mm length (or 8 magnets of 10mm diameter, 5mm thick)
• M8 nuts/bolt/washers
• Something to mount the door stop onto. Adding mine is of no use, every situation is different.

Mounting the door stop:

Place a M8 bolt nearly parallel to the door where you want the door to stop. The M8 bolt should be 20mm above the lowest point of the door. In my case the door is 60mm above the ground where the door stop is placed. My door stop is also made on those dimensions. If the door is even higher than 60mm, no problem. If it is less (55mm might still work, less will not!) the foot step will rest on the ground but the wig that enters the groove will be too high for the door to pass over it. A solution will then be to shorten the foot step. 

Press the magnets into the 4 holes on the door stop and the little bar which is to be pushed into the groove on the bottom of the door. Please make sure the magnet poles are in a way that the magnets in the door stop will attract the magnets in the bar (which is to be placed in the groove)
