External hard disk holder for laptop

I would like to have a holder to keep safe my external hard disk when I use it on may laptop, and I didn't find one so I design it. It easy to customize to adapt for different harddisk size or different laptop screen

It is more easy to print base and cover separately.
Join with glue.
