Which fasteners and how many of them should we use? The description says (M3 * 8mm) X 9, but I've counted 17 screw holes (4x for Adruino Uno, 2x for the RTC clock, 5x for arms/servos, 4x for the front panel and 2x for the top cover). Also the video tutorial mentions that arms shoud use M3 * 6mm.
It would help greatly to have a separate table listing all needed screws list with type, counts and purpose. Perhaps this (or similar) set should also be included into the shopping list: https://www.aliexpress.com/item//1846309705.html. Thank you.
