This is an SCI-quality 3D print file (1.9MB). Scale model enthusiasts can use this file to "push the edge" with the new wave of 3D printing.
This is a standard file for use on basically any new 3D printer out there. Developed, tested and recommended for use on an inexpensive FDM (Fused Deposition Modeling) printer using yellow ABS plastic. No support material is required. When printed in plastic, this non-warping MAG Boom component makes an improvement in the Voyager SCI Kit.
Not everybody has a 3D printer, or can use the one at work or at school. But there are also 3D printing services available separately, and are easily googled. You send them any .STL file such as this one, specify a material, and pay them to print it out and send it to you.
