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.

GLB Shaft Coupler StarForge 3D Modeling Software

Motor Shaft Coupling for CNC and Robots

GLB, the Binary glTF file, shows a 3D part in a web page through three.js or model-viewer, so the GLB Shaft Coupler helps a maker documenting a CNC, robot arm or printer build online let readers spin the exact coupler used. It joins two round or D shafts of different diameters, Rigid or Flexible Spiral, with each bore 0.2 mm over its shaft and an M3 set screw and nut trap on each side. StarForge 3D Modeling Software also makes the same coupling as a 3D Print STL File, printed standing up for 3D printing.
