Bolt & Nut Design & Drill toy compatible

I modeled the bolt and a nut for the Design and Drill toy. For the threads you'll want to lower the layer height a little. I've tried 0.16 and 0.12 and both seem to work well. I'm learning and having fun with this. Feedback letting me know how your print went would be greatly appreciated.If you're feeling generous and like what you see, Send me a tip.
