About this 3D model
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. Cheers, Red Beard Ops
