Reduction for use of Kappa lock in topcase from Shad

I have motorcycle cases from different manufacturers and wanted to have all cases with one common key. I got the extra lock for the topcase for the kappa side cases, I got the one from another company (SHAD SH39) and the lock doesn't fit. So I figured out a way to reduce it.
It requires 3 parts. I printed with a 0,25mm nozzle.
It's easy to assemble, it shows in the pics.
