I bought a 5170 some time ago and the floppy drive was just being held by the case.
I want to add a 3,5" drive too so again the same problem: the L shaped clips are missing.
I've found the dimensions to make them from aluminium, metal,... but maybe someone has a file to 3D print them?
There are files for the rails but not the clips as far as I see.
Or maybe has some spares 😀?
