A simple leg for a table

I wanted to build a table for my indoor green garden, but i could not find one that fitted my needs so i made a simple model of this.
The leg is in three pieces, one top that are supposed to be screwed to the table. one piece that is the leg itself. that piece can be repeated for a higher table.
and one foot.

I recommend the top and bottom pieces to have solid layers in the flat pieces for best strenght.
