Carbon Nano Tube pen holder 3D print model

A pen holder with a single-wall carbon nanotube shape with metallic prosperity. The pen holder features some defects like actual carbon nanotubes. I studied carbon nanotubes in my MSc and admire their shapes. The bottom includes some details about the nanotubes (Preview2). If you're also a fan of carbon nanotubes, place the pen holder on your desk.
