I designed this model to have a more compact solution for your own house keys. I designed it to have up to 3 keys but in most cases I found going with the single option or the triple option to be the most requested and used. there will be some support material to remove but I found easy to remove with needle type tweezers. this model will hold together with friction but over time will work out of the housing. I recommend using super glue to fix the parts in place. the Key on the slide should hold in place without any gluing.

Feel free to remix for your own purposes.
