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.

STEP Shaft Coupler StarForge 3D Modeling Software

Motor Coupler for Lead Screw Assemblies

Mechanical designers lay out stepper motors and lead screws in Fusion 360, SolidWorks, Onshape or FreeCAD, and the STEP Shaft Coupler drops a matching coupler into that assembly as STEP, the ISO 10303 exchange format. It is a faceted mesh, not an exact parametric CAD solid, so it checks fit and clearance rather than giving an editable feature tree. It joins two round or D shafts, bores 0.2 mm oversize, with one M3 set screw and nut trap a side, in Rigid or Flexible Spiral Style. StarForge 3D Modeling Software saves a 3D Print STL File as well for 3D printing.
