The file 'Swiss Army Knife Style Key Holder 3D Printer Model' is (stl) file type, size is 93.2KB.
I didn't have any screws to use the available designs online, so I just made my own.
I used 3 M4x12mm screws (no nuts) to hold 6 keys.
The file "swiss army key pt 2 v2" is the one I used, but if you want to modify this design for your own purpose, I included the files "swiss army key for modding" and "swiss army key pt 1 for modding" which can both be easily changed in TinkerCad to fit different screw sizes and numbers of keys.
