Description
UPDATE 06 August 2025
First set of attachments is released to build a longer version of the Arca Ignis.
The set contains a longer Handguard, two different front grips and a longer Picatinny Rail.


Bring your prints to life this summer with the Arca Ignis Water Blaster, a fully 3D-printable, modular water gun based on the original Arca Ignis rifle design – now reimagined for the Bambu Lab Electric Water Spray Kit.

IMPORTANT: The parts in in the red boxes are not needed for this build.
This isn’t just a decorative prop – it’s a functional, splash-ready summer gadget that blends detailed design with real-world fun.

Assembly:
A detailed step-by-step video guide is available here on YouTube, covering installation of the water spray module, tubing, and tips for assembly.
Print the Tube Tempate and cut the tube to the right lenght of 30mm.

IMPORTANT: When installing the silicone tube from the Bambu Lab Water Spray Kit, make sure that the tube extends about 2–3 mm into the lower receiver. This ensures a secure connection to the magazine and prevents leaks or pressure loss during use.
How to load the battery:
Simply remove the grip including the battery and load it via the included USB cable. Once loaded, reinstall the grip.

Coming Soon:
Additional attachments and upgrades are already in development!
Thanks to the modular design, new parts can be added or swapped out easily using a plug-and-play system. Whether you're looking to customize the look or enhance the function, future add-ons will give you even more ways to personalize your Arca Ignis Water Blaster.
Disclaimer:
This is a prop-style water blaster designed for casual use only. Use responsibly and avoid spraying toward sensitive electronics or people unprepared for battle.
