The models were repaired and checked for printability.
I really hate when I am running and my keys are ringing in my pocket that's...Show more why I designed this simple minimalistic key organizer. Thanks to that your keys are always in the same order, take very little space, and don't ring while you run.
I recommend printing that with PP to make it strong, to mount the keys you will also need an M5 screw and a nyloc nut.
Measure the thickness of the stack of your keys and choose the closest STL file (for example if your keys in a stack are 8.8mm go with simple_key_holder_9mm.stl).
You can also find .F3D file so that you can edit it and adjust to your needs!
