Móc tròn có đế phẳng để dán/keo lên tường

Hello, 

I removed the sqrew hols in blender, since my grasp of modeling in blender is not great there is a hole in my model that is visible on layout table. The gap is microscopic and slicer with 0.4mm ignores it so I didn't fix it. I think it will be ignored for any standard print.

I taped my hook with foam tape and it worked great to hold cycling helmet.
