we juge that the prototype was good so we make on boxes.py a wooden box for a better design.

We enter parameters on the site and cut it on wood with a laser machine that I learn to use the first semester during the ernergy course.

A new questionning arrives : how to manage the opening with the servo ?

we thought about elastic to pull the lid by behind or use cable to wrap aroud the servo but it was a fail.

The last idea we had was the put the servo inside the box and attach on the servo a 90° rod fixed to the top to push and pull to open and close the box. Ignoring why, even if the structure was correct it didn't work. The servo wasn't strong enough to pull the lid so we change for a stronger servo but the problem persists.

With the 90° rod, we decide to not fix it on the lid but tilt it forward for an opening less than 90° so the cover is simply placed on the rod which, when it turns, will make the cover fall and then push it to open it without tipping the cover too far back. That how our mechanism works.
