This handle is for use with miniature carving chisels like these from Micro-Mark: https://www.micromark.com/Miniature-Chisels-Set-Of-7

I found I wasn't using these chisels as much as I wanted to because of how hard it was to get a good grip on such a small tool when needing to apply a decent amount of force like when modifying or cleaning up 3D prints. This handle can be used to better secure the chisels for more control. While you could scale the handle up or down as needed, if you print it with 3 or more walls, you can just drill out the hole to the size you need for a tight fit. If you scale the handle, you'll want to also scale the base. As my chisel set came with 7, the base is configured to hold 7 as well.

Notes:

Print with at least 3 walls to ensure the handle is sufficiently strong.
