Bought a new TV set that is able to record to an external USB HDD. Had some WD Elements drives at home, connected and it worked well! Problem was only, that the TV was mounted on the wall and zip - tie the drive to the arm of the mounting set did not do the job very well! So I created that wall mounting device for the HDD - Drive, works very well for my needs!
Added the 123 design file as well so you can adapt it to your needs! Have fun... ;)
