The North Castle Library is excited to offer 3D printing services to the public!

You can use the software of your choice to create your own projects. While there are many free online CAD software available, we use TinkerCAD in our workshops (www.tinkercad.com). Also, see TinkerCAD tutorials and instructions for software help.
