 * Make the base with its half-round hole and make the 2 half-sided and the 2 half-folds separately.
 * Then make 1 extension on 1 of the sides of the width of the opening minus 0.1mm, the 2 edges thus remain separated.
 * Then on this extension (in green) draw the contour of the cut and make 1 pocket
 * The result is the red piece above, and the unfolding works, stays the line that separated the 2 edges previously
