Hummingbird v2 SIG Style Folding Stock

prusaprinters

This is a folding stock that plays nice with the Hummingbird v2 nerf blaster!It is by default made for right handed nerfers, but if you flip the stock attachment point upside down you can make it left hand friendly as well (the button will just be on the top instead of the bottom).Build instructions are the same as the original design, except there is no longer any picatinny attachments for the stock or the mount point. The stock attaches to the swiveling piece with an M5 nut and screw. The adapter attaches to the back of the blaster using 2 M3x45 pins. If you have modified your Hummingbird to add additional stock pin holes, I have added support for those in to the attachment point as well. The button uses a small M2 hex screw to screw in to the top of the flag. Add a spring between the button and the attachment point and the button to make the stock automatically lock.The only part I had to sand was the little protrusion from the swiveling piece that helps it hold its position on the stock. Sand that down a little bit on the sides and it should mate up perfectly and be really solid once screwed down with the M5 screw.  If you want you could definitely make this design smaller and more compact, I just didn't have any interest in doing that. I just printed everything at 0.2mm using Prusament PETG and it worked great.Have fun!
