I printed Rmod's Skeleton stock and didn't care for some of the aesthetics and print method. I changed the profile of the attachment location to match flush with the stock attachment of the Nerf Stryfe. I also combined the two halves and made it vertically printable. The length ends up being right at 240mm. There is no need for hardware to attach. This thing is a super snug fit and takes a little force to slide all the way on. Be sure to make use of the triangle towards the back to add a custom logo or embossing using something like tinkercad. If you are wondering what the random hole on the top is for, I needed to be able to see my voltmeter that is embedded in my stock attachment.
