Wired profiles Athey Moravetz, a game developer who quit the business to raise her kids, who built WarpZone, a massively successful Etsy store selling 3D printed, nerdy cookie-cutters:
While many homemakers have a secret cookie recipe, Moravetz has a small fleet of MakerBots. Her four MakerBot Replicators run simultaneously to keep up with the demand for her products. She says "I turn the bots on when I get up in the morning to get my daughter ready for school. So they turn on about 8 am, and they're running all day long from that point until an automated timer I've got them plugged into, turns them off at 3am. That way I can get in one last print started as I'm going to bed."
...Designing cookie cutters requires design skill — not every game character makes for a good cookie. Moravetz says "I had a lot of people requesting Dr. Who stuff — Tardis and Dalek specifically. A Dalek just doesn't read unless you include the inner detail — the silhouette is only readable to a certain degree. It needs the inner detail. But it needs a lot of small inner detail, and I try to avoid cutters going over three and a half inches in any direction. I made a four inch Dalek, but it took nearly two and a half hours to print, and when you're getting as many orders as I am right now, any cutter that takes that long to print is hardly worth it." Like Dr. Who, she outwitted the Dalek and now offers it for sale alongside the Tardis.
