CM Stacker mounting brackets

Got this Cooler Master CM Stacker a while ago. problem: parts are missing and i cannot install any hard drives. 3D printing to the rescue.Model provided as is, i've printed it flat, in PLA, so those flimsy studs (see pictures) are prone to breaking. maybe try to print it on an angle or use PETG for better layer adhesion.My measurements might be a little off and i've made the studs a bit shorter according to my own needs. feel free to remix this. this is my first model i've uploaded,
