Sometimes you need to get into a small space with a screwdriver. While my Wiha bit set had an extension that worked nicely, I didn't have anything to get into much smaller spaces, so I made one!
What I came up with features a magnetic base to securely hold your bits, as well as a knurled surface (video includes a brief clip about how to accomplish knurling on a cylinder).
Step 1: Print and Assmeble
If you'd like your own, all you have to do is print it out based on the STL found here and obtain items outlined below:
Bits, like the ones that come in this set (Amazon)
6mm x 1mm magnets (eBay)
Filament, I used Ziro marble (Amazon)
- 3D Printer—mine (Amazon)
Once printed, you'll need to press a pair of magnets into the non-hex side of the holder. I used the spindle of my milling machine, but there are many ways to do this.

Step 2: Use
The driver makes a nice way to get into really tight spaces, and could certainly have other uses. If nothing else, I was glad to finally learn how to make a knurled surface.
