DEFAD is back at it! This week we've got incredible projects ranging the full
gamut of DIY Defense. Right out of the gate we have the Nylaug from Because2A and
friends, which is a full receiver and hand-guard system for converting your surplus Steyr
Aug kit into a great ghost gun! Designed to be printed with ease (minimal supports), with an
emphasis on cutting edge 3D printing technologies (heat-resistant nylon filament), this nearly sci-fi build is sure to turn heads at the range.
Parabellum returns with the publication of the second version of
his Hybrid 9MM platform: Panther-9 MK2 SMG. This project takes the best of 3DP and
hardware firearm design and trims all the fat. The good professor has delivered a simple and cheap design, assembly guide included, that only relies on hacksaws, drills, and an angle grinder.
out the week's more prominent new releases with his
B40/B69 DIY Grenade Mega Pack. There are so many recent
developments on the grenade
front as of late, and this pack delivers with a variety of MILSPEC systems for
fragmentation, smoke, and flash. You can download all these exciting projects at DEFCAD today!
Ghost Guns sells build kits, fixtures, uppers, stocks and lower parts kits to finish
every 3D and DIY weapons system on the market. The items we carry are the ones we use
Enjoy this week's sales across our line of Aves Rails kits. The most
popular ghost handguns are based on the DD.2 series of frames, but they require
machined components, and our Aves rail kits are currently the most deeply-disconted online. If you’ve been on the fence about doing your first Ghost Gun build, the time has never been better!
Ghost Guns also sells the popular FGC-9
Complete Build Kit at the best price on the Internet! Everything you need for the FGC-9 MK II (aside from printed components) is
included, so pick yours up today and get printing!
S2 Underground is a prominent Youtube account which has been steadily posting
intelligence updates and useful tips and guides for the coming troubles. He recently
released GhostNet, which is an overarching term for a collection of
networks set up to allow users around the world to exchange information without relying
on pre-established infrastructure.
We recommend you watch the video, download the system, and get your

The Plastic Power: A Speech
Cody Wilson, the founding father of 3D printed guns, delivers a speech on the uses of history, misreading and profile creation in 3D gun culture. He addresses Freeman's folly, the death of JStark, and how to overcome the creative exhaustion and impotence of 3D groups like The Gatalog. You can

IR-Illumination for NVG
In DIY Defense it's important to study the techniques and tactics of modern war. Learning every piece of leverage we can puts the "asymmetric" in asymmetric warfare, and one of the largest pieces of leverage is being able to decide the time and place of
engagement. If you can see in the dark, and your opponents can’t, someone has a leg up to say the least.
The designer Knack has improved projects in the DIY NVG space and has made both his
own vision system, the PVS-69M, and an illuminator/pointer known as the GAL. There are
extreme limitations to night vision at this price point, so it's imperative to have some
manner of amplifying ambient light sources without working in the visible light
These projects represent the tip-of-the-spear in the DIY NVG space, and its exciting consder what Knack
will publish next. Both of his projects are fully documented and exacting in their instructions, and they set a meaningful standard in personal defense.
This is the start of a series covering the most relevant settings and considerations for
3DP as it relates to DIY Defense, ranging from material and printer selection to post
processor settings and part treatment.
"Infill" refers to both the pattern of the print lines and how dense that pattern of print lines
actually is. There is also some consideration for how many lines constitute the boundary
of the part and how thick those lines are. Infill will determine just how strong and
flexible a part is as well as how much material a print will require and how long it
In terms of DIY Defense there are essentially two options to consider. The first option
is "30%-50% infill density" which is for parts that will not experience significant load
(and if they fail there will not be a catastrophe). Think along the lines of grips, stocks or
otherwise ornamental parts. This infill setting, or lower, is also good for rapid
prototyping for testing the fitment of your designs.
Our second general option will be "90%-100% infill density", which we reserve for major
components, and those designed to contain or absorb the shock of gun parts in contact with explosive
forces. This setting will mean that most, if not all, of the space taken up by the part
will be filled with filament. While this makes our parts much stronger, it tends to take 2-3x
times longer and, similarly, 2-3x more material.
For everything else, a good rule of thumb is to use "Gyroid" (as illustrated in the banner), which has one of the best balances of strength, speed, and material usage. But feel free to
experiment with “Tri-Hexagonal” or "Cubic Subdivision."
The final strength setting, thickness, will be decided by our nozzle size, but overall
we can go with 0.4 mm as long as we're sure of oour wall settings. We can
access these by navigating to "Show Custom" and accessing the "Wall" subsection. Set the
Wall Line count to "6" in most cases and ensure wall thickness matches top and bottom
These general guides should help you get started with most 3DP projects on DEFCAD, and we hope you'll enjoy more in our coming newsletters. For more introductory material like this, be sure to check

Handbook of Weaponry
The DEFCAD Documents Collection is slowly becoming mountainous! While it is a small niche, in terms of
engineering materials, our selections are of incredible quality.
additions to our collection come in the form of both volumes of Col. Whelen’s Small Arms
Design and Ballistics. These texts were written in 1945, and its general coverage
design and function are clearly articulated. Featuring refreshingly clear diagrams and explanations,
this 300-page exploration of American firearm design is a joy. Keep an eye out for updates to the library and feel free to contribute texts
that you think every designer in our growing space should read.
