i need to make this piece for my dustcollection on a machine. i am not a pro and i am using blender to create this but blender seems to difficult.

i dont know what is easy to use.

if i want to export this model i need te repair it but then it will fill de bottom. if i dont repair it it wil fill the whole thing as a solid block.

and i want it to be much smoother then it is right now
