Mechanical Nerf Stock Adapter

prusaprinters

A stock adapter with a functional lock similar to molded stocks that fits N-STRIKE style lugs. The tube was designed for use with the ‘Buffer Battery Stock’ and buttplate from Flygonial's ‘Gryphon’ blaster, mostly because it's a perfectly good stock and I had a spare sitting in a box from an earlier Gryphon build. I've included an updated locking pin that does a better job holding the set position on this tube vs the stock pin. Included are some slicer screencaps showing that the adapter should be printed upside down and only the perimeter lines really need to be supported, assuming your printer can do average to decent bridging. Support removal is pretty awful if the entire face has supports under it and often the bridging layer separates during removal, which affects tolerances. I print on Elegoo Rapid PETG on an 0.4 nozzle and have set the body dimensions to work well with that so I can't speak to dimensional accuracy on other filaments except to say that PETG is known  to shrink more than PLA so it may or may not be sloppier in PLA. The main point is that the bottom features of the adapter body that the lock slides along need to be as accurate as possible, so printing horizontally with the open side up doesn't really work. Also, on a printed part you have to accept that the slide lock will have more resistance vs a molded part as it zips up and down along print lines. Tube length is 225mm because it was intended for adult use with a shorter pistol style blaster and most stock tubes tend to be shorter for use with rifle style blasters; however, with the stock in the shortest position it's generally not too long. Step file is included in case you want to adapt it for a different stock tube or change to an arbitrary length or whatever.  I've set a non-commercial license mainly due to it functioning similarly to commercially available options and IDK if that's an issue or not. Again, to complete as pictured you just have to print Flygonial's stock and buttplate parts:https://www.printables.com/model/208101-the-gryphon-foam-dart-blaster/filesBattery Stock\Buffer Battery Stock.stlBattery Stock\Buffer Buttplate.stlBattery Stock\Buffer Buttplate Hook.stlHardware:6x - 10mm M3 screws to fasten tube to adapter (Must not protrude from recess.
