About the harp

This is a small playable harp, a remake of an older harp project by the same designer, released into the public domain. Everything prints without supports, and it fits on a Prusa Mini+ bed.

It's strung with ukulele strings: one pack of tenor ukulele strings should do, cut into shorter lengths so you get more strings out of the pack. Printed friction tuners are included, but the designer says you're better off with geared tuning pegs, as long as they fit (the holes may be too close together for some). You can tune it however you like. A STEP file is included if you want to change the design; the designer's demo video linked from the page is no longer online.
