Model a checker game piece
Create a 3D model of a checkers (aka draughts) game piece. The piece must fit in a 2.25" (57mm) game square and be under 4 inches (100mm) tall. The pieces should be round and have a diameter between 1.0" (25mm) and 1.5" (40mm).
BRL-CAD provides several ways to model 3D geometry including a graphical tool named mged, another named archer, and various ways to create geometry using scripts. Create your model using BRL-CAD, not via import. You should have one top-level combination (e.g., checker.c) without any overlap errors reported by 'rtcheck'. Give your model a title (via the 'title' command) which should include your name.
Start with MGED tutorials if you haven't yet, which are separate tasks! You can learn the basics of 3D modeling in just an hour or two.
SUBMIT a PNG image, your geometry in BRL-CAD ".g" file format, and a text explaining how&why you made your model the way that you did. Whomever submits the most interesting design may get their model included in future releases of BRL-CAD.
