HDD Stacker v4.0 John

try to put supports on it for a cleaner print, i'm currently trying to make a slim one for use(not compatible with this version. for peoples who ask why it is on v4.0 this is just the version i made that that fits perfectly. i use normal m3.5 screws that are used for desktop drives., i made this design for 3.5 drives but is compatible to occupy 2 2.5 drives.
