A zero-hardware half-dart Katana/AF Pro magazine adapter for the Dart Zone Spectrum/Adventure Force Thunderbolt. It uses a dart head as the spring - I've been using accufakes, but anything squishy should work. You can use the original internals from the source model, but I've also remixed those as to be a bit more stable and a lot easier to disassemble if needed.

Tested and working magazines include the Katana magazine (duh) and the 1st gen Adventure Force Pro short dart magazine (the one included with the Nexus and Aeon Pro). 

It's unclear/untested if the magazines included with the DZP MK blasters or the Omnia are compatible, as I seem to have misplaced them. 

Incompatible magazines are anything with Talon geometry or catch location, including the new Adventure Force x-magazines included with the Nexus and Aeon Pro X, the ones included with the Adventure Force Dictator, the official Nerf Pro short dart magazines included with the Stryfe X, and the ones included with the X-Shot Longshot Pro. 

Supports are only needed in one spot, as seen in the photo above. I'd highly recommend using tree supports, with the branch density set to 100 percent and the top interface layers set to two.

Notes:

I'd recommend using something a bit more temperature resistant if you're taking this to an outdoor game, as at least where I live, the interior of cars will get hot enough to warp PLA.
