Swiss blade keyholder

I made this neat organizer for my keys, it helps to have more space in your pockets and to make less noise with your keys :)

I used a coulpe of nuts and bolts, I´m not sure their correct naming but the measurements in the holles are 5.5 mm and the nut from one side to the next is 9.2 mm (I added a picture).

I added the STEP files in case you want to edit them and make your own!

Also, make sure to use a some washers between the keys, even ir some keys are bigger than others you can still use this, just add more washers, in the third picture you can see that I have a big key on one side and 3 keys on the other.
