Hands up anyone who is constantly mislaying their keys. That'll be me because I usually end up failing to do 3 or 4 things at the same time (who said multitasking is easy!)
I made this highly visible, giant keytag for my shed so it was easy to spot in the clutter that builds up on my workbench, a tidy desk is a sign of a sociopath.
The room 219 is faithful to Stephen King's novel and the room 237 to the film. Print whichever you think will help keep people from going in and "borrowing" tools which never get returned.
The body or base is at 3mm with the text and border 2mm higher, so colour change at the end of layer 15. I print them with PETG and 0.4 nozzle. Infill can be minimal as strength isn't a factor on something like this. Time saved not looking for your keys is more time to make models for printing as well so win win.
The author hasn't provided the model origin yet.
