MAIN PURPOSE: Amplify a paper-strip music box movement

A resonant case for a hand-crank paper-strip music box movement. Screw the movement to the floor, the crank comes out of the side, the punched song strip feeds in at the front and out at the back, and the thin walls and sound port make the little comb far louder and warmer than in your hand.

Resonance Ring

MAIN PURPOSE: Let a singing bowl ring freely on a point rest

A rest for a meditation singing bowl. The bowl sits only on the inner points of the scalloped ring, so almost none of its body touches anything and it rings far longer than on a cushion, while the grip feet keep the ring still when you strike it.

Kapok

MAIN PURPOSE: Stand a flute or recorder upright on its foot joint

A stand for a flute or alto recorder rooted like a rainforest kapok tree. Six plank buttresses flare from the trunk, so a tall, top-heavy instrument stands on a wide footprint that weighs little; the 17 mm peg goes up inside the foot joint and the collar takes its rim.

Jacaranda

MAIN PURPOSE: Play a pair of seed pod castanets

Castanets from a seed pod. Jacaranda pods are round woody shells that children clack together; print two of these cupped valves, tie them through the stalk holes with cord so the rims face each other, loop the cord over your thumb and snap them with your fingers.

Tine Box

MAIN PURPOSE: Build a kalimba resonator for a tine kit

The resonator body of a 17-key kalimba. A 140 x 84 mm hollow box with a round sound hole in the soundboard, two wah holes in the back for your fingers and a raised rest bar for a standard tine kit, braced inside so the top stays flat. Add a tine and bridge kit and play.

Wax-tuned pentatonic pan flute

MAIN PURPOSE: Play and tune a pentatonic pan flute

Eight closed pipes 100 mm deep, labelled A5 to D7: tune each one with a tuner app by dropping in beeswax or Blu Tack until the note is true, just as Andean makers tune with wax. The rounded rims are kind to the lips and every pipe is re-tunable.

Guitar strap lock washers

MAIN PURPOSE: Stop a guitar strap slipping off its buttons

Push the round hole over the strap button outside the strap and slide it sideways into the narrow slot: the button head is trapped and the strap cannot pull off, so the guitar never drops mid-song. A cheap fix for every strap and every guitar.

Studio monitor tilt wedges

MAIN PURPOSE: Aim and decouple desktop studio monitors

Four TPU wedges under a desktop speaker tilt the tweeter up about 4 degrees towards your ears and decouple the cabinet from the desk, so the bass stops booming through the furniture. The lip at the low end keeps the speaker from sliding.

Music stand page clip

MAIN PURPOSE: Hold sheet music open on a stand outdoors

Hook the clip over the ledge of a music stand and let the springy arm press on the open pages: the music stays put in a draught or outdoors, and the arm flexes aside with one finger for a quick page turn.

Guitar soundhole humidifier pod

MAIN PURPOSE: Humidify an acoustic guitar from inside

Fill the slotted pod with a damp sponge and hang it in the sound hole from the 120 mm bar, slid under the strings: the guitar breathes moisture from inside, where it matters, so the top does not crack and the frets do not stick out in dry winter air.
