Hands Free Door Handle

I created this hands free door handle to open a door in an office. The latch was already disabled, but you still had to grab the knob to open the door. This allowed the door to be opened easily with an arm. The hole pattern was designed to fit over two existing screws from the deadbolt. I added the 3rd hole, which needed to be drilled into the door, because it was developing a crack (See picture). With the 3 holes, this has lasted 4 months made from ABS with constant use.
