I made this Thing based on the design for the eyelet of a Salvi harp. My own (budget) Gear4Music harp had all its eyelets broken over time, and I needed replacements. I could not find good eyelets, but I got something close to what I needed from a harp vendor.
I took that design and parametrized it so you can change it to your needs. It's important to get the right diameter for the soundboard hole, so it may take some experimentation for your specific harp.

Disclaimer: I'm not responsible for any damage to your harp, but I do hope this Thing pronlongs the useful life of many harps.
