nerf
I've been heavily involved in the nerf hobby since February of 2024, when I built a Caliburn 4 using a hardware kit I got for Christmas. Ever since then, I've been hooked on building 3D printed blasters.
Here's a list of some of the cool nerf projects and builds I've made (ordered based on vibes, not chronology):

Minima
A fully custom nerf blaster designed for simplicity and low cost.
Closed loop Protean
The world's first(?) closed loop nerf flywheeler using brushed motors.
Full length Skewer
A remix of the Skewer that uses full length darts. My first major nerf related project.
