Testing angles and V cut

This is one part of the chair, there are four sides with this type of shape. So, to get the shape i want, i have to make V cuts on each side so that it can fold properly.

Here is my first attempt :

First Attempt

I made the angles too big so all side did not come together closely as you can see there is gap in between.

Here is my 2nd attempt :

Second Attempt

In 2nd attempt I successfully made it :). The V angle was smaller so all side are coming together as one.
