screw container for parametric model maker

This is a simple customizable screw container with a slightly fancy knurling, but you can use MakerLab's Parametric Model Maker (or OpenSCAD) to change the size and some knurling options to adapt it to your needs and taste, just click on the “Customize” button. Diameter and height are inside dimensions in millimeters. Give a few tenths of tolerance for the planned content. Update: There's a new version available, with much more knurling options: parametric screw container v2.
