This towel hanger can be hooked onto the top of a kitchen door.
Designed for 19mm--20mm depth door.
I attached the FreeCAD model, so if your kitchen door has different dimensions, you can modify the model to fit your door.
You don't need any additional parts. You can print all the parts, including the hanger bar.
After you print, please glue all parts.
