Print Keep Squire is a beginner-friendly, front-loaded single-shot foam-dart blaster, designed for those eager to venture into the exciting world of 3D-printed blasters!
Its my first blaster design, next one is coming soon!

Blaster specs:
The Squire is a simple springer, utilizing a cut-down K25 spring as a power source and an aluminum barrel. Its minimalistic and comfortable design requires a small amount of filament. It comes stock with low-profile sights, but you can customize it with accessories like red dots and grips, thanks to the M-LOK compatible handguard. The end result is a well-performing blaster capable of long-range shooting, delivering up to 2 Joules of power (~210 fps muzzle velocity).
Assembly:
Assembly is quick and easy, requiring only a few parts and approximately 27 hours of print time. The comprehensive manual listed in the files below ensures a crystal-clear building process for everyone.
