This is The Pigeon, a mag in handle, semiautomatic nerf sidearm. It was intended to be a sidearm, not a primary, but hits a surprising 100+ fps. It isn't the most accurate or powerful, but the goal was capacity, rate of fire, and ease of use, which is has in spades. This is a great compliment to out of the box blasters like the Spring Thunder, or high capacity, low rate of fire blasters like the Caliburn.
These files are all one piece, and so not all printers will be able to fit it. I may upload some cut apart pieces, but I don't recommend printing it that way. A Prusa mk3 and larger will print it all in a single piece for the shell. Print orientations should be what I've saved them as, but feel free to experiment. There is likely some post processing needed on a few spots, particularly the slide and barrel guide and pusher mount, and the trigger's nub that interacts with the flippy arm part.
To print one for left handed use (the slide lock on the right side of the blaster for hitting with your left thumb) print the LH slide parts, and flip all other parts in your slicer horizontally.
For hardware it uses standard nerf screws (stryfe size) a very small extension spring for the mag release(~3/4" long), a longer one for the trigger(Under 1/4" diameter and 1" length), and an even longer one for the slide(~3/16" diameter and 1 3/4" long). For the mag release, you will need some kind of pin. The ones I've been using are 3/32 by 3/4, and are just slightly too wide to close completely.
I recommend using Make Test Battle Honey Badgers for the flywheel motors because on a 3s they can hit the necessary rpms to hit higher velocity in this setup. I recommend a turnigy NanoTech 1300 Mah 45c 3s, https://hobbyking.com/en_us/turnigy-nano-tech-1300mah-3s-45-90c-lipo-pack.html but it can potentially fit certain graphenes or other 3s batteries.
Wheels are available from Flywheel the World, who designed the cage system that this blaster uses. https://www.facebook.com/flywheeltheworld/?fb_dtsg_ag=AdyZae0Ropdtib4cXahBb3DkfBs61tloBfhN1bOlvpWR4w%3AAdyuhBAV63OSO7BN9l1OJ5QPILhxIaKT4bUHUHWgdvZ00Q
-I'm including the version 6 files, as I haven't tested v7 quite as extensively, but 7 should have better switch interaction. Both will work, but version 6 will probably need a stronger trigger spring than v7.-
If you're interested in purchasing one, you can check my store https://www.etsy.com/shop/MHPArms?ref=seller-platform-mcnav where I will be listing them periodically as I build them, or buy a printed version or kit from my friend Derrikk's store: http://blogderrikksun.com/product/mhp-dessert-pigeon-3d-prints/

If your printer can handle the bridging, print with 10-13% infill on supports, and a 70 degree overhang. This will use less supports and have a good finish, especially on the slides. I also recommend using 3 walls or solid infill on the slides, as they undergo a lot of abuse with the return spring.
Trigger and mag release should be printed solid, and the mag release should be printed sideways to give it the maximum strength. The trigger can be printed upside down from how it's oriented by default, or on its side, which will use less supports, but leave a poorer finish. If printed sideways, it may be more prone to breaking.
