The Splattershot is the default weapon from the upcoming Nintendo game Splatoon. After being revealed at Nintendo's E3 Direct, I was eager to create something from this fun little game, so I chose to have a go at creating the ink gun that's used as the primary mechanic. I'm a fan of making functional props, so it was also a fun challenge for me.

Since I only had the single game trailer and a promo art piece for reference, I started building the gun around the template of a 2L cola bottle as the main holding tank to set the key scale I would be using for all my pieces. Comparing this bottle to the tank used in the game's version, I was able to slowly build up each part of the gun in an accurate scale to the original.


  • Fires water from a detachable 2L bottle at the top of the gun through a 12v windscreen washer pump
  • Air intake valve to the bottle to prevent pressure building up
  • Trigger-activated
  • Master power switch behind the grip
  • Removable AA (or 9V) batteries for easy replacing/recharging
