Storing Machine - based on prusament spool (upcycling prusament)

This is what I call a Storing Maching, it's a robotic spool tower, which has a mecanism in it that open and closes the drawers via the rotation of a nema 17

Purpose:

Pressing a button help you select one of the 4 drawer, the whole tower rotates to always open the drawer facing towards you or on the side, but never in the back

Each spool level is shifted by 90 degree to prevent two drawers to open one above the other

The goal is to re-use a maximum of empty prusament spool
