Wishbon 2 - A Tool for Sharpening Small Drill Bits

It was always difficult for me to sharpen a drill with a diameter of less than 3 mm. Most of the available tools for sharpening drills are not designed for this, and manual sharpening was not always obtained. Sharpening drills with a diameter of less than 1 mm did not work at all.

Once I came across a description of a little-known tool Wishbone for sharpening small  drills and I decided to do something similar, but suitable for manufacturing on an FDM printer. The result is Wishbone 2. This tool allows you to quickly and efficiently sharpen drills with a diameter of 4 mm to 0.5 mm without any special skill.

Made using 3D printing on an FDM printer, easy to assemble, inexpensive.
