Here is an STL file and an SVG file either for laser cutting or 3D printing.

These are mini wind chimes. Assemble with string as shown in the image.

I used conductive paint and conductive thread to make these actuate triggers using the MaKey MaKey. You can see my project at Instructables here:

I edited the image from the original SVG I designed to accommodate people using a 3D printer using Tinkercad. You can edit the 3D model here:
