At heart a simple cylindrical screw container, but pimped up by lots of knurling options. Use the customizer to get the box of your needs with the knurling of your dreams :)

Edit: As of a request, I added a version that allows a string to be attached to the lid. This takes away some inside space, depending on desired string diameter. This is a new SCAD file; use it with the parametric model maker or OpenSCAD.

Printing: I recommend splitting into objects and using slightly different layer height for body and lid (e.g. 0.20mm/0.17mm) for smoother operation.

I also like to use octagram spiral bottom infill.
