The Amazing M3 Hex Nut Stuffer

So... How many of you have ever had to try and put a hex nut down a long shaft? How many times did you drop that hex nut in there in the hopes that it would land flat only to dump it out and try again? Well this is the solution and it works 100% of the time. I call it "The Amazing M3 Hex Nut Stuffer". If you guys find it useful, let me know and I'll make other sizes. I usually only work with 3mm nuts.

How cool is it that you can design and print a tool you need on the spot??
