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 Pen Holder StarForge 3D Modeling Software

Pen Cup for Desk Organizer Designs

STEP, the ISO 10303 format of Fusion 360, SolidWorks, Onshape and FreeCAD, lets a pen holder join a larger desk organizer design in CAD. The STEP Pen Holder writes the cup as a faceted mesh, not an exact parametric solid, so it is for placing and checking fit rather than editing features. Diameter, Height and a Pattern of plain, Hex or Slot set the shape; walls are 2.4 mm and the floor 3 mm. StarForge 3D Modeling Software also gives a 3D Print STL File, sized for pens, markers and an Apple Pencil, ready for 3D printing.
