We just fixed downloads: every STL now comes straight from fast, reliable storage, saved under its own name, we're making 10,000 STL files and dozens of new tools, so things might break. We'll fix them ASAP.

STL Shaft Coupler StarForge 3D Modeling Software

Lead Screw to Stepper Motor Coupling

The STL Shaft Coupler joins two round or D shafts of different diameters, such as a stepper motor shaft and a lead screw, and saves the coupling as a 3D Print STL File, the Stereolithography mesh every slicer reads. Both shaft diameters are typed and a Style picked: Rigid, or Flexible Spiral, one piece that bends. Each bore is 0.2 mm over its shaft, with one M3 set screw and nut trap per side bearing on the D flat. StarForge 3D Modeling Software makes a motor coupler that prints standing up for 3D printing.
