Adjustable Screw Driver

A simple manufactured sheet metal tool with a pair of two different screw driver blades. Especially to open / close central nuts of clock dials for wall- and longcase clocks. You need only four components: a screw bolt, a winged nut and two sheet metal parts, whereby the sheet metal parts are the same. A tool, remodeled from an existing product, I found in my toolbox. I thought, it's so simple as well as effective for use, to share it. Uploaded 3D-data: STEP-file of the assembly PTC-Users: (.asm)-file with included (.prt)-files in a "zipped" folder.
