1/4 inch drive Bit Holder

thingiverse

To suit my needs for various 1/4 drive bits in my power screwdriver, I've tested multiple bit holders seeking a tight fit with numerous holes and a lanard loop. After trying different hole sizes, I found my preferred choice. For printing, set the parameters to 1 shell at 0.2mm layer height and 20% infill. If it's too tight, use sandpaper on a 1/8'' bit to make adjustments as desired.
