About the harp tuning key
Harpists tune constantly, and a spare key is handy. This printed key fits Lyon & Healy, Salvi and Venus lever and pedal harps, costs about 75 cents to print, and has room on the handle for an embossed name or design.
The designer recommends PETG for strength. A PLA prototype also worked fine but may not last as long. The supplied 3MF and G-code add a brim and extra perimeters around the bit. Do use the brim: without it the part is likely to come loose and make a mess.
