Printed mine in bulk PETG and draft mode, no need for fancy layers or support. It is possible to mount the drives with M3 screws, but I dont thinkt that is needed.
Uploaded a few variants if you dont want to use openscad to change the parameters.
The model in the pictures is "P510_SSD_6_ridge".
I did this model mostly due to space economics, and that I needed the drives a bit further "down" to be able to use Y-cables for the power.
The author marked this model as their own original creation.
