I tend to lose my drum tuning keys (..and guitar picks, but thats another Story), and had nothing to make it stick to the drumset. Now i have, it snaps in perfectly and holds tight.
made for a Tama Key with 7mm and 10mm Diameter and 2,54mm (1 inch) Hardware to be snapped on.
with 40% infill in Cura with 2 Walls + 1 extra skin wall printed with a .4 Nozzle on an E3Dv6 it feels perfectly solid and snaps in with a good sounding click! ;)
