Shirt Buttoning Tool

I have a friend who suffers from a very rare nerve disorder and as a result his fingers don't work precisely enough to do buttons on dress shirts. I initially looked at this thing (https://www.thingiverse.com/thing:1105309) which showed promise, but it didn't seem strong enough for his shakey hands. So I made what I think is a better one (with apologies to the original designer, lukeskywalker58)

To use this one slide slip the loop over the button and then thread the smaller end through the button hole and pull the tool and the button through together. To work effectively the tool needs to be thin, so if you find resistance print one with a scaled down height. The default thickness should work for most people though.

There print quickly (a couple of minutes) and are dirt cheap, so I printed my friend a bag full of them.
