Input
Prompt
Design a single-body ergonomic pen, 100 mm long, optimized for long writing sessions. The pen should have a solid body with a single, clean internal cylindrical tube running from the front nib opening through most of the pen’s length, but sealed at the back (only the front hole should be open). Pen body must remain solid everywhere except for this single internal tube. Internal tube: inner diameter 2.8 mm, length 90 mm. No hollow space anywhere else inside the body. Front hole should align precisely with the tube opening. Smooth matte finish, lightweight, and ergonomic finger grooves at the front. Ensure the internal tube remains visible and intact when exported to STL and opened in Ultimaker Cura (it must appear as a clear internal cavity, not a full hollow body). The model should be 3D-printable and manifold, with consistent wall thickness around the tube.
