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.

AMF Pen Holder StarForge 3D Modeling Software

Pencil Cup That Holds an Apple Pencil

Long before 3MF caught on, ASTM and ISO pitched AMF as the format to replace STL, and PrusaSlicer and Slic3r still open its XML with the millimetres written in. Someone who archives every desk part that way can keep a pencil cup in the same folder: AMF Pen Holder shapes it from a typed Diameter and Height, plain or with Hex or Slot cut-outs, on 2.4 mm walls and a 3 mm floor that keep an Apple Pencil from tipping. For slicers that never learned AMF, StarForge 3D Modeling Software offers a 3D Print STL File for 3D printing.
