Sturdy Doorhanger for Heavy Coats

I did not know where to hang my winter coat so I tried some door hangers I found on thingiverse. Most of them broke immediately or after some days - my coat was just too heavy. Other looked quite robust, but I did not like the design.
So I made something sturdy but simple to print. This door hanger holds my coats for some months now without the slightest sign of breaking (fingers crossed).

Recommendation:
Print with 50% infill (or more) and three walls.
