The door's width is 43.8mm. I did mine with a 15% Gyroid infill, which was fine for clothes; if you want to hang bags, I suggest a higher infill.
The author remixed this model.
I adjusted this for the width of my door, and the gap at the top, and also remade more or less the model for better fillets. Also, it was too high for my wife, so I made it longer and added an additional hook.
