Washboard exercise

I made the grooves by extruding and beveling different parts of the flat cuboid

and the other parts are simply made up of Cuboids of different sizes

I leveled and aligned the cuboids in place

The grooved board and the back is put together

I copied a piece of the cuboid(the one in contact with the Grooved board).

And placed it at the opposite end of the grooved board

I then made another longer cuboid and placed it at the sides of the washboard.

And VOILA!

Reflection: In this exercise, the alignment part is easy, but the groove board is slightly harder, but it's nothing we all cannot handle.
