This is a simple and quick to print ssd mount.
I couldn't find one that just changed the fixing holes spacing on the bottom of 2.5" drives to the 3.5" drive spacing, so here is mine.
The holes are all 3mm. this should allow the 2.5" drive screws to easily pass though to the drive, and the larger 3.5" drive screw should self tap into the outer holes.
The mount is a slim 2.5mm thick, but as ssd's are incredibly light this seems to be plenty.
Print settings are not critical, probably 3 shells (1.2) 0.2mm layer height.
