Liberating the 3D Printed Gun

The Liberator

Yes, yes, we now have 3D printed guns, and our world has changed because of it, right? Right.

I’ve written about 3D printed guns before, and I’ve talked about 3D printed guns before, and now they are (somewhat) possible. But don’t be frightened, as there is little new here.

Andy Greenburg at Forbes has been leading the pack on the story of Cody Wilson and Defense Distributed and their attempt (and success?) at 3D printing a gun. And OH NOES! Now other people are printing guns! And some of them are even improving them, but this should be no surprise. Hackers and makers see something that needs improving, and they improve it. When I saw the files for the Liberator the first thing I thought was that it needed work. After I talked to someone who is well versed in 3D printing and gunsmithing, they agreed.

I want to toss out this quote from HaveBlue again:

The one point I try to make (and that they generally fail to grasp) is that if it eventually becomes possible to download a file from a website, feed it to a printer, and have a fully operable handgun a few hours later, the technology will have already impacted our lives in far more incredible ways.

So has our world changed? Yes, I think it has… As I mentioned recently in Your 3D Printed Future, people have created open-source designs for mechanical finger prosthetics. Yeah, that’s pretty amazing. We’re not talking about medical companies charging thousands of dollars for mechanical finger prosthetics, we’re talking about a couple of really awesome people working together on this, and creating something you can 3D print yourself with a sub-$1000 3D printer.

What else is there? Well, bioprinting is progressing nicely. Boprinting sheets of skin for skin grafting procedures, bioprinting a replacement bladder, bioprinting replacement for missing bone for a human skull, and even bioprinting part of a face!

(The joke is that you’ll be able to print out a replacement hand for the one that gets blown off by your 3D printed gun. It’s only half of a joke, because it’s pretty close to being true.)

Now, back to the gun issue. I highly recommend the Hackaday post: The first 3d printed gun has been fired, and I don’t care. Right now the Liberator is little more than a zip gun, which is a simple (single shot) gun that anyone with access to a local hardware store could build. But don’t worry, you’ll be safe:

In late 2000, British police encountered a four shot .22 LR zip gun disguised as a mobile phone, where different keys on the keypad fire different barrels. Because of this discovery, mobile phones are now x-rayed by airport screeners worldwide.

Sigh… more security theater. Just what we need. Do we need regulation on 3D printers? No, just like we don’t need regulation on lathes and mills and hardware stores. So here’s the deal. I have the file for the Liberator, and I’ve held a Liberator, and I’m not a bad person, and I hope to never, ever shoot another person in my life. Why? Because that’s not the type of person I am, and that’s not the kind of world I want to live in.

As for the Liberator, it’s a crappy gun, and if you want a good gun for cheap, there are dozens of ways to get one, both legally, and illegally. And if you want to make one, there are also better ways to go about it than 3D printing one. If the novelty of a cheap, crappy, plastic gun intrigues you, go ahead and print one. Try not to blow your hand off in the process. Guns are dangerous, and even a well made gun can malfunction.

3D printing is all the rage right now, and the media loves hype because it means more attention, more page views, and more dollars. So yeah, go 3D print something, maybe a gun, maybe some mechanical finger prosthetics. Just follow this one simple rule: BE EXCELLENT TO EACH OTHER.

Be Excellent to Each Other.

MaKey MaKey Apple Piano [code]

Makey Makey Apple Piano

I’m one of those people who say “I’ll publish that code later!” and then I get busy with other projects and never publish the code, so here’s me publishing the code.

So back in January I built the MaKey MaKey Apple Piano for one of Art Milwaukee‘s events that the Milwaukee Makerspace was involved in. And yeah, here’s the code!

MakeyPlayer

I’ve provided the Processing sketch and related data files, as well as full applications (for multiple platforms) for those who don’t want to mess around with compiling sketches, and just want to download and run an application for their MaKey MaKey.

Could it use improvements? Of course it could! Feel free to make it better, and if you do, please share your changes with others.

A Coat Hook

Coat Hook

I recently (temporarily) changed offices at work, and with the new office came a new door, and this door has no coat hook! Because I couldn’t drill a hole in the door or mar the surface in any way, I needed an “over the door” style coat hook. Ah yes, the classic coat hook. Adrian Bowyer made one back in 2008, so I decided it was time to make my own.

OpenSCAD Coat Hook

I took a quick measurement of the door to determine how wide it was. I then fired up OpenSCAD and made a bunch of “cubes” of various shapes and sizes, some rotated 90 degrees, but all in all, a pretty simple OpenSCAD model. One thing I did do was add in the “door” based on the measurement I took, so I could see how the coat hook would fit around it.

Plate Coat Hook

After compiling it in OpenSCAD, I exported the STL file, and at this point I usually use Gary Hodgson’s STL Viewer to take a quick look at the file and make sure it’s oriented correctly.

G-code Coat Hook

After viewing the STL file, I use Slic3r to generate the G-code, but hey, let’s check out the G-code while we’re at it! Joe Walnes wrote a great web-based G-code viewer you can use online, or download and run locally. If you want a somewhat improved version, Jeremy Herrman’s got a viewer and some code for you.

Working Coat Hook

Well, after all that generating files, and viewing files, I printed the file. It worked out well! Here’s a terrible photo of it preventing my shirt from falling on the floor. Success! The magic of a home 3D printer pays off again.

Make: Lego and Arduino Projects

Make: Lego and Arduino Projects

Leave it to me to forget things! I forgot to mention that my Arc-O-Matic was mentioned in the book Make: Lego and Arduino Projects. Get to chapter 3 and you’ll see one of my photos.

I should mention that I have not actually read the whole book, I ended up loaning it to someone who is way more into LEGO and Arduino stuff than I am, but if you want more info on it, WIRED has a nice write-up, and you can buy it from Amazon or directly from O’Reilly.

John Baichtal (one of the authors) has another book in the works which I’ll have a hand in, but we’ll save that story for another time.

Flying Cars and Robots

Flying Car MKE

Remember Milwaukee Innovation Week? Sure you do, or maybe you don’t, it doesn’t matter because it’s been replaced/re-branded as Flying Car Milwaukee!

June is a super-hectic month around the RasterWeb! World Headquarters, and even more so in 2013, but that didn’t stop me from submitting a proposal to their Great Robot Showdown contest, and yeah, I got accepted, and I’ve got less than a month to finish building the robot I’ve proposed. There’s nothing like a deadline to get things done!

So besides getting a presentation ready for WordCamp Milwaukee that weekend, I’ll be attending the Flying Car Gala on Friday, June 7th at the Potawatomi Expo Center to show off my creation and hope it doesn’t burst into flames before the prizes are handed out.

If you’re not into robots but enjoy fashion, design, or film, there’ll be plenty of those things as well. (But seriously, if you’re not into robots, why are you even reading this!?)

There’s a ton of other stuff going on during the week, just check the events page. If you’re interested in making the world a better place, join out friends at Bucketworks for the BuildHealth Workshop. And if you happen to get in on the Innovation Factory Tours you may see me building the aforementioned robot at Milwaukee Makerspace.

(June’s my month… you may not be able to avoid me! Mwuhahaha!)
