This is my modular wardrobe. It is made of three parts. By printing the middle piece several times, it can be extended as needed. Each element can be screwed into the wall, whether this is necessary depends on the weight that is to be hung on the wardrobe and the wall in which the screws must hold. Of course, the hooks can also be printed as often as you like. I have printed the coat rack including the hooks from PTEG. Whether a 100% infill for the hooks is necessary is to be decided depending on the application.
