The 6th prototype in the Kanetana line. This one basically works the way that I expect the 1.0 to work, and it's the first since 0.3 to have endstops on the dart door action. The dart door also got a longer dart contact radius, which helps keep the magnets closer throughout the travel and makes the whole thing even taller. Most of the further development will be making these more durable and efficient 3d printed parts with more and better mounting options.
Like 0.3 thru 0.5, this requires a nerf drum replacement spring from foamblastshop.com and a 12mm x 3mm neodymium magnetic disc.
