3d printing model toilet paper holder created for wall mount. You also need any plastic pipe or cylinder ( diameter 20 mm and length 14-15 cm) and m3 screws 14 mm long or shorter and nuts for them. Use 0.2 mm resolution (But you can try something else. It doesn't so much matter). Rafts: No. Supports: No. Infill: 40% (But if you want it so much heavier and stronger use 60-100%) Use STL for your slicer program. Use base part as shelf and left side or right side as pipe holder. Base part sliced made for divided printing if it more fits you. But you need to mirror it.
