USDZ Pen Holder StarForge 3D Modeling Software

Desk Pen Cup Previewed at Real Size

Holding an iPhone over the desk shows the pen cup at real size, because USDZ Pen Holder saves the design as USDZ for Apple's AR Quick Look, with no app to install. Diameter and Height are typed and a Pattern chosen: plain, Hex or Slot cut-outs. Each holder has 2.4 mm walls and a 3 mm floor, sturdy for pencils, markers or an Apple Pencil. Once it looks right beside the keyboard, StarForge 3D Modeling Software provides the 3D Print STL File for 3D printing the pen stand.
