The process
Firstly we print the plan, by the help of plan we measured and cut the cartons in the right sizes and shapes. 
We made a hole with skewers on the cartons at its perfect places, and attached the cartons to each other before the glueing them together and made highlights the places that need to glue.
At the next part, we super glued the skewers to cartons at right places and made it sure that the arm is moving.
But at the end, we came across an issue that the syringes were too small for the arm because we used an A3 sized base instead of an A4 to solve the problem we rearranged the syringes so the arm should move.
