Ultra lightweight hdd adaptor.bought one of these ( https://www.conrad.nl/nl/hd3402jsc-35-inch-sata-hdd-behuizing-usb-30-esata-417037.html ) . To have some extra backupspace trough all drives I have laying around. one of 'em was a 2.5" so i needed this. Found some adaptors that where a lot of wasted filament. so voila. LVM is awsome for multiple hdd's as one single volume!Should fit others as well sinve dimensions are derived from sata standards.No source files because I've drawn this with a cad license , not owned by me.
