I thought about making one, but didn't because I picked up some Weber ones free, while acquiring grills. Before that, I had a cheap one that was annoying me.
Here is one version

As
@YardBurner's post suggested, you could just cut the top & bottom out. Just put newspapers (or whatever) in the bottom and coals on that, tilt the can slightly to light the newspapers & eventually lift the can straight (maybe using some pliers, oven mitts, whatever). You could even get somewhat fancy & make a handle or just drill a couple holes near the top you could temporarily hook)such as with a coat hanger & lift).
