Hex bit needle file handle

I created this file handle because my new files came with ugly handles that didn't fit into my current holder. I also wanted a better handle "feel" than the standard needles file come with.

I created three handles to start with. The goal was a light press fit bore without glue. The 3.2mm bore handle worked great for my diamond files from an unknown Amazon supplier.

The shape is modeled after a standard 1/4" hex bit. I wanted to use standard "quick" hex bit handles in my shop.

Main bore size (bottom step= .1mm - bore)
- 3.0 mm
- 3.1 mm
- 3.2 mm
