I have 2 doors that open towards themselves that do not hit the wall in the same spot. Space is a bit tight to use those half ball rubber bumpers and I didn't want to have to buy 2 flat wall bumpers. I made this to accommodate the 2 door knobs so they won't destroy the wall and allow the doors to open the maximum I could. 

Use double sided foam tape for affixing to the wall. Could use Command Strips if wanted but it better if the entire back part is supported behind to keep it from breaking it. Measures approx. 9"x5". Hope this helps someone else and if it does please post a comment :-)
