Hex bit needle file handle

thingiverse

I crafted this file handle to accommodate the unsightly handles that accompanied my new files, which wouldn't fit into my existing holder. I also aimed for a better feel than the standard needles file comes with. To begin, I designed three handles. The objective was to achieve a light press-fit bore without using glue. The 3.2mm bore handle worked exceptionally well with my diamond files from an unknown Amazon supplier. The design is based on a standard 1/4" hex bit. I wanted to utilize standard "quick" hex bit handles in my workshop. Main Bore Size (Bottom Step = 0.1mm - Bore) - 3.0 mm - 3.1 mm - 3.2 mm
