knurled-nut-driver reviews and mentions

• Any idea what is the name for a tool that can close those nuts properly? Anyone have found one at Aliexpress perhaps? Thanks!

  I've been meaning to 3D print one of these - your post prompted me to get around to it. I forked this design and added a handle, since the original is designed as a drill attachment (which isn't a feature I wanted). It works okay for tightening finger tight. Note that the design has some complementary knurls inside the socket to grip the nut, but they are too fine in detail to print on a typical 0.4mm nozzle. Despite this, it grips well enough (I did use a light fuzzy surface in Cura to try and add some grip, but I don't think that made much of a difference).
