![]() Check out the video below of the gun in action. What do you think about this automated gun? Discuss in the 3D Printed Rubber Band Sentry Gun forum thread on. All in all, this is quite the creation for a young man who has only owned a 3D printer for about 2 years. Other than the 12 3D printed parts, which Thomas has made available on Thingiverse for anyone to download, the gun requires several nuts and screws, a threaded bar, a skateboard ball bearing, 30 cm of string, several pieces of metal pipe, and the various electronics mentioned above. The gun, if made correctly, has a shooting range of about 5 meters, and its design was inspired by a sentry turret seen in the Portal 2 video game. MPF Bid Sample combat vehicle and 3D visualization of the MPF prototype. The 3D printed gun was designed by Thomas using Cubify Invent, over a period of three days, and then the parts were 3D printed on his bq Witbox printer using PLA filament. In particular, in lookingat the turrets externally, there appear to be many. Thomas used a software package created by Project Sentry Gun in order to control his creation. It allows the gun to easily find and shoot any moving target, all by itself. ![]() “I used an Arduino Mega and for the motion the sentry uses two servo motors, one micro servo 180° for the tilt (y-axis) and a normal one for the pan (x-axis). “The ‘Automatic Rubber Band Blaster’ gave me the inspiration to design something similar but automated,” Thomas tells. Thomas has, for a long time, desired to create something of this magnitude, but it wasn’t until he saw a design on Thingiverse for an Automatic Rubber Band Blaster that the light bulb went off in his head. The model he created is capable of shooting 24 rubber bands in succession, although he tells us that it can easily be adapted with a larger barrel to fire up to 30. Thomas, however, elected to use this model to create a fully functional rubber band version of the gun. This certainly is the case with the 3D printed Rubber Band Sentry Gun, created by a 20-year-old student from Bienne, Switzerland, named Kevin Thomas.įor those of you who are unaware, a sentry gun is a firearm that can sense targets and then fire upon them. It seems as though each and every rendition of these toy guns is a little bit more intricate and functional than the last. Easy and fast - check them out.Here at, we’ve covered our fair share of 3D printed rubber band guns over the course of the past couple of years. Their online tool gives you price up front, let’s you pick the materials etc. Where to print? If you don’t have local access to 3D printer then we can heartily recommend our partner i.materialise for any kind of 3D printing jobs. 1/6th scale might do the trick and keep the back leg strong enough, or if you have the skills then make the back leg a bit chunkier for 3D printing. The most important thing to note is that the back leg is seriously fragile so either go with a really strong material (stainless steel or better yet, titanium would be good but pricey option). Notes about 3D printing a Portal turret model Then there’s a foldable paper turret created by Mike McDermott that you can download from .įinally, if you’ve played Portal or Portal 2, have you ever wondered what does a typical day for a turret look like? Wonder no more ’cause you can get a good answer to that important question from the following video. Something being made out of a Lego is a sure sign that something has reached pop culture stardom and of course there’s a tutorial available of how to make a Portal turret out of Lego blocks. I wish more companies had such a creative approach to ads. I’ll kick off with the official Portal 2 trailer. Fortunately there’s tons of interesting stuff around the Portal’s turret in the internet. Sign up, download, 3D print.īefore I dig into the finer points of 3D printing this mechanical creature on 3 very wiry legs, let’s have some fun. Over 700000 creatives worldwide making things like shirts, stickers, phone cases, and pillows weirdly meaningful. Want to own one? We have the models - Portal turret for Solidworks and same turret for AutoCAD. And for a very good reason - they’re deadly, yet perfectly adorable. With the release of Portal 2 all the gaming fans have gone a bit turret crazy.
