WhistlePop

WhistlePop - Blow the whistle, pop the cap.

Every now and then I try to fulfill requests. Many of you have written to me asking for it, and here it is: WhistlePop is the keychain gadget you didn't expect: a high-powered whistle and a bottle opener in a single, minimalist and lightweight object.

Designed for those who don't want to choose between utility and style, WhistlePop combines two essential functions in a compact form. The built-in whistle is extremely loud, perfect for emergencies, sports, hiking, or simply making yourself heard, while the snap-on bottle opener works great with every use.

Main features:

Very Loud

Integrated bottle opener

Fast printing: just 20 minutes

Extremely lightweight: just 8 grams of material

Printing tips:

If your PLA isn't strong enough (depending on the brand you're using or if PLA is old and damp), increase the infill to 30%.

Recommended PLA+, tested with Bamboo filament and works perfectly, obviously higher resistance materials will have more durability over time.
