Hi Anis,
As Paolo mentions,
Shell in MoI works better on more simple geometry, so it's better to plan your modeling steps when shell comes into the picture.
You should try and apply small details like, fillets and small ledges as shown in the picture, after the shelling operation as these areas tend to be difficult for shell to calculate.
I've also remodeled your part, using solid cylinders and preforming the shelling operation before the small details and it shells nicely, at a range of thicknesses.
You will find the steps in the .3dm file attached.
Cheers
