Mini Whistle – Extremely Loud (115dB) – 1.5g Edition

This Mini Whistle – Extremely Loud (115dB) – 1.5g Edition is a slightly larger, sturdier version of the original mini whistle, still small enough to disappear on a keyring. Weighing in at 1.5 grams, it prints quickly and comes off the bed fully functional — no assembly needed — while delivering a genuinely deafening 115 dB, tested with a sound level meter (see test video/screenshot).

It's not just a novelty print — it's a real safety whistle you can clip to your keys, backpack, or bag for emergencies, hiking, camping, or everyday carry, with a bit more material for added durability over the ultra-light 0.5g version. Key features: - Print-in-place — no assembly required, comes off the print bed fully functional.

- Lightweight — only 1.5g, still barely noticeable on a keyring.

- Quick print — fast enough for batches, gifts, or giveaways.

- Extremely loud — tested at 115 dB, exceeding many commercial safety whistles.

- Integrated keyring loop — attach directly to a keychain, ready to carry immediately.

Printing tips: - Print in the same orientation shown in the photos (whistle lying flat, keyring loop up) for the cleanest print-in-place result with no supports.

- Use a 0.12mm or 0.16mm layer height for the cleanest surface finish and best acoustic performance — finer layers help the internal air channel form cleanly for a stronger, more consistent tone.

- PLA works well; a slightly stiffer filament may hold tone quality longer with heavy use.

A slightly beefed-up version of the mini whistle — still pocket-sized, still extremely loud, with a bit more heft for everyday durability. Dont forget to like and follow! Thanks!!
