Peep Whistle
Loud, one-piece, nothing inside to rattle loose. Choose your pitch before we print it.
Ships in 3–5 days · printed to order in the color they pick
No magnets, no batteries, no paint — raw name-brand filament only. Recommended ages 5+.
Original Xeno 3D design
The full story
A proper loud whistle with no pea inside — which means no small part that can ever shake free, and it still cuts across a soccer field. We tune the chamber to the pitch you pick when ordering, so siblings can have provably different whistles and settle that argument forever. Fair warning to parents: it works. Made to order in-house, finished by hand, and checked over before it ships. Need a color, size, or finish you don't see here? Drop us a note and we'll sort it out.
Material & care
Printed in premium PLA+ or PETG depending on application. Wipe clean with a damp cloth. Avoid prolonged direct sun for PLA+ items; choose PETG or ASA for outdoor use — just ask.
