Uses a M3x10 or 12mm button head or phillips head or could be modified for a socket head cap screw.
Attaches to the Dewalt 12v drills/impact/screwdriver and allows you to slide on/off a Wiha belt pack bit holder which uses a dovetail type system.
Printed with the dovetail up and support to fill the cavity. I printed out of ASA for durability.
The author marked this model as their own original creation.
