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.

OBJ Shaft Coupler StarForge 3D Modeling Software

Motor Shaft Adapter for Robot Builds

Blender and most modellers import Wavefront OBJ meshes, so the OBJ Shaft Coupler suits a robot or printer build being laid out or rendered before parts are made. The coupler links two round or D shafts of different sizes in a Rigid or Flexible Spiral Style, with bores 0.2 mm over each shaft and an M3 set screw and nut trap on each side, the screw bearing on the D flat. StarForge 3D Modeling Software also saves the motor shaft adapter as a 3D Print STL File, which prints standing up for 3D printing.
