Madeup is going on the road for the first time tomorrow—at our local public library. Participants are going to create their own models and we’re going to try printing them. Since many models exhibit printing issues (too steep an overhang, intersecting geometry, non-manifoldness), we’ve generated a handful of objects that are well-behaved.
