After buying my first gel blaster from AliExpress, I absolutely loved it—just not the refilling part. I searched around for a solution that suited my taste but couldn’t find one, so I decided to make my own.

Keep in mind, I’m no designer. This was my first attempt, and I aimed to make it printable without support structures. I’m not completely satisfied with the result, but it works.

If it doesn’t fit your build area, the optimal printing angle should be between 28 and 29 degrees.
