keychain memo switch

have you ever had that thought of having forgotten something? maybe that thing that you do so lightly because you've been doing it for so long that you don't notice it? it has happened to me yes, even too many times. it has happened several times to be back home from work hours ago, and in a moment of tranquility, for no apparent reason, to have that magical doubt of having left some room open in the workshop where I work. since I'm tired of having these sudden anxiety attacks I made this customizable memo switch.its operation is very simple: there are six colored drawers with two colors, which once moved can give you a report on what you are doing, to be able to check them in case of doubt.for example I wrote the names of the various rooms in the workshop, and based on the color of the drawer I can understand if I closed them or left them open. assembly:The assembly is very simple: you will need 24 4x2mm magnets that will fit two in each drawer, and 12 on the main body. th
