There are 3 different versions of these files handles with 3 different inside diameters (they are labeled 1-3 on the end of the handle). The needle files I made these for had a shaft outside diameter of 0.1135''.

1 = Very Tight - (honestly this is the one I like… even though they take a while to get on with some twisting involved)

2 = Tight - (this was likely the factory fit)

3 = Loose - (too loose for my application, but I figured I'd add another version for slightly larger shafts…. note you can always scale these up and down to fit your needs!)


I printed mine with no brim and PLA+… 35% fill but this was probable not needed.
