The DeWalt Li-Ion cordless drill (model DCD710) has become my "go to drill", favoring it over my larger models. It's very small, fits my hand well and is surprisingly powerful. My only complaint is that it lacks a clip to hold a screwdriver bit. This 3D part solves that by adding a screwdriver bit holder to the side of the drill.

STL along with Solidworks, OpenSCAD and Step design files are included.
