Simple Protection for tables corners.

Only 3 parameters + 1 flavour (shape modifier)

h : the internal height of the protection (table thickness) ep : this is both sperical ray or thickness of the part around the table w : width / length f the part (in x/y direction).

thin: 1 or 0, two different flavours

Default for h = 8mm suitable for some glass tables.

20170724 Added thin parameter Added rotation so the thin version can be printed as is without rotation

20170724 Thin version looks a lot better, and is more effective, added protection ray for that But ... rotation to the part is horizontal has disapeared. You need to rotate under cura for thin version :-(. I have to spend time to learn how to compute this (any voluntarely ?)
