Summary

this is why i love 3d printing. Our magnet mount of the door was complete broke. so i put the pieces together and start drawing. I made a new one in less than 2 ours whit printing time. So thanks to the 3d world i don't need to replace the hole door. Works great.
The original magnet door mount had some more plied so the old close a little bit easier. But the new one works fine like it is now.
