The [TuneFast Harp](http://makefastworkshop.com/hacks/?p=20171213) is a 3D printed musical instrument that uses a single-string to create an 8-note diatonic harp.
The total cost with all hardware is under **$7 per harp** and only takes around **3 hours to print**.
Hear what it sounds like with a **metal string** https://youtu.be/fx9zlmGFXBQ and with a **nylon string** https://youtu.be/yGjTQOmBWsM.
**UPDATE:** A **new version** of the harp (*AHarp22_v04.stl*, shown below with blue PLA) has been modified from the original to include a **parabolic sound reflector** (focusing the sound 8-10cm away from the string) and a clipped corner (to reduce total material used). Files are also included to print your own M3 washers and the final M3 spacer to reduce the parts list a bit.
