The file 'Flat WDT Tool 3D Printer Model' is (stl) file type, size is 1.1MB.
This is my version of a flat WDT tool that can easily be shipped.It's heavily inspired by jkim_makes original people's WDT tool, as well as his business card WDT.
Assembly is pretty easy, and I'll add a tutorial at some point when I have more time.
