Precision screwdriver holder for gridfinity.  This is specifically for the hexagonal handled drivers.  Most gridfinity ones are for the round handles, I prefer hexagonal.  Mine are Injora RC hex screw driver set.  Amazon Link below.

The fit is tight so you can pull the set out of your toolbox and take it with you.  You don't have to worry about them falling out.  

THE PHOTO HAS A TYPO:  There is 1.27mm twice.  That is fixed in the actual model to be 2.0.
