Here is the spun text: Why you should support me on Patreon https://www.patreon.com/Ultrasonic2 These are the files for the updated Stryfe stock (Version 3) I made version 2. I have changed everything but the major improvements are improved stock sliding mechanism and a "crush" type stock to receiver mounting system. AR15-reciver_extension.STL The crush slot for the mounting bolt has a 45 degree taper so you can print this vertically and enable supports from the base and as long as your angle is greater than 45 then it won't support in that gap which could be hard to get out if it did print in there. The bolt is a M4 45mm with nut. After printing the above print Normal_Size_Test.STL This is a profile of the stock you can make this first to see if it fits AR15-reciver_extension.STL... if not print Normal_Size_Test_025_over_size.STL and try that one... After that print the right size Stock AR15-main_stock.STL/AR15-main_stock_025_oversize_.STL I have made two versions because everyone hates making things that don't fit. So now you have two options.. FYI I printed AR15-main_stock.STL You can then print the latch AR15-stock_latch.STL If you want you can print AR15-stock_swivel.STL and AR15-stock_swivel_screw.STL for some more eye candy. However, I haven't printed these yet and it's unlikely they will be able to support any weight.. I'm assuming you'll glue the screw in. The Stock to receiver still needs more fine tuning in bolt length and Spring. I believe I used a M4 "Flat" head screw driver screw that was about 35mm long. You then print MD_m4_pin_lock.STL and slide it over the bolt. I wasn't sure what spring would be best so I bought a range of them, but I still feel they are too weak. I used a 50mm wire with a 0.4mm outer diameter and 7mm stainless steel small spot compression. I would go for something shorter but with a significant increase in wire diameter next time.. ID can be 4mm and OD can be 8mm, well that is the space provided not suggesting a spring of those dimensions. I would like to hear back from the community on a better spring weight and bolt length. The nut needs to be a M4 LOCK NUT.. not what I used in my pic/video m4 Lock Nut http://s.click.aliexpress.com/e/UjUfEee The license you agree to when downloading this thing prevents you from making a profit from MY thing.
