Meet the Pocket Splash Pro 

— the water blaster born from a challenge: Could a powerful water toy be made in less time than a lunch break and for less than the price of a candy?

One (HOT) summer afternoon, with temperatures rising and kids already planning epic water battles, an idea appeared. Instead of buying an expensive plastic toy that might break after a few uses, a simple empty bottle and a quick 20-minute 3D print became the foundation for something different.

The result was surprisingly powerful. By attaching the lightweight printed nozzle to almost any standard bottle, an ordinary drink container transformed into a reusable water blaster in seconds. Empty bottle? Swap it. Need a bigger reservoir? Use a larger bottle. No complicated parts, no expensive replacements.

What started as a quick experiment soon became the star of backyard battles, beach trips, and family gatherings. Friends wanted one. Neighbors asked where they could get it. Everyone loved the idea of turning everyday waste into instant fun.

The Pocket Splash Pro isn't just a water gun—it's a story of creativity, sustainability, and making unforgettable summer memories from something as simple as a bottle.

Around 20 minutes to make. Around 20 cents to produce. Endless hours of fun.

Assembly:

Cut a piece of PTFE tubing to the desired length. Depending on the size of the bottle used, it must reach the bottom (for a 1/2 liter bottle, this is approximately 18 cm, for example).

Press the PTFE tubing into the Ø4mm hole until it stays in place.

Fill the bottle with water and then screw the cap with the tubing onto the bottle.

The PTFE tubing used is the same as that used in the Bambu and other printers: Ø4mm outer diameter and ± Ø2mm inner diameter.

Usage:

Simply squeeze the bottle to aim a powerful stream of water at your target.

Thanks to the addition of the PTFE tubing, the bottle can even be used horizontally, and even a half-filled bottle will produce a stream.
When using, try to ensure that the end of the tubing is positioned horizontally at the lowest horizontal position so that you can spray the bottle completely empty!

Thanks to the standardization of caps for PET bottles, almost all PET bottles can be used!
