Top Shelf Shopping Hook for Wheelchairs/Mobility Devices

As everyone in a mobility device knows, everything you really want in a grocery store is on the top shelf. I am not a fan of grabbers because they are too big and cumbersome and often provide poor grip. I like to simplify the problem so I realized that essentially, I just need something to pull things off the top shelf and catch them. 

I developed my first prototype three years ago, fully expecting to make several more versions, but I fell in love with it on the first try. I have now gone through a few as they sometimes hooked up on the bus and snapped with terrific force(great tensile strength) or gotten misplaced in the hustle and the bustle of shopping. I fully credit JipCutter for the intial design, it really is something.

The tooth can hook onto boxtops and dig into plastic packaging, providing excellent grip. I have received compliments from every store employee that has seen it. I just haven't found the best way to mount it to the chair yet.

I recommend four walls and 25% gyroid infill. No supports required, but if you set it to make overhangs printable, the tooth will be structurally reinforced. 

I liked the design of the back scratcher but saw its potential to be used for other things. I used it as the basis for a simple shopping hook for use by people in mobility devices. The handle is direct from the original author.
