This tool generates a pen holder at the diameter and height you type in and exports it as an STL. Choose the body shape, set wall and floor thickness, add compartments if you want them, and the model updates in the browser so you can spin it and check.
A pen cup is one of the first things most people print, because it is quick and nothing has to fit anything else. With twist, angled rim and side pattern options, the same template produces either a plain office cup or a decorative desk object.
Free, no sign-up. Change the sizes in millimetres and download the STL.
Each variant is the same template with different settings. Follow the link and the editor opens with those values.

Twist rotates the body as it rises, which gives a spiral effect on faceted cross-sections. It makes no visible difference on a round body, so pair it with the square or hex shape. The panel automatically limits twist when the side slope would pass 45° and tells you the new value, so the part stays printable without supports.
The slot pattern cuts fine vertical openings and uses the least material; the pointed tops close without support. Honeycomb gives a face that is both stiff and decorative, while round holes produce a softer look.
For a single-compartment office cup, 70-85 mm diameter and 95-110 mm height work comfortably. For brushes, 60 mm diameter and 140 mm height is more useful.
At 0% infill, 2 perimeters and 0.2 mm layers, an 80 by 100 mm cup takes 2-3 hours on most printers. Printing it in vase mode with a single wall roughly halves that.
The openings go right through the wall, so fine dust can escape. That is harmless on a desk, but if you expect pencil shavings, turn the pattern off and use a plain body.
Twist tilts the side surface, which would tilt the openings too and leave their bridges unprintable. That is why the side pattern is dropped whenever twist is above zero.
This tool generates a cylindrical cup defined by four numbers and exports it as an STL. Enter the outside diameter, height, wall thickness and floor thickness in millimetres, and the model is computed in your browser ready to download.

This tool generates a divider box at the outside dimensions you type in and exports it as an STL. Enter width, depth and height, pick the number of rows and columns, and the divider walls split the interior into equal cells while the model updates in your browser.

This tool combines a silhouette, a cross-section and a surface texture into a parametric vase and exports it as an STL. Enter height, body diameter and wall thickness in millimetres, pick a texture, and the model is computed in your browser so you can spin it and check.
