If you need to cover the pipe from the kitchen hood and the size of 200 mm in height, 250 mm in length and 190 mm in width will suit you exactly, this is the model for you! (Or you can adjust the size in the provided Blender file.)
The bottom hole is 120 mm wide, 61 mm high and is 50 mm from the back. The thickness of the side of the cover is 5 mm.
The exact dimensions can be seen in the picture.
This model uses the maximum model width (250mm) that the MK4S can print.
I am attaching the original Blender file in case you want to make modifications to the model. The thickness of the model and the rounding of the edges are made as Blender modifiers, so you can easily edit the basic mesh that defines the dimensions of the cover.
The author marked this model as their own original creation.
