3D printed airsoft Claymore

This is the most recent version of my airsoft Claymore. I had done four others but they were messy, unreliable, and difficult to build. For this one, everything was designed beforehand to the last millimeter. I’ve tested it a few times during matches and it works reliably.
It has movement detection and throws BBs with enough force to be noticeable within 5 meters, while also beeping and flashing an LED. It can be autonomous or remotely operated.
Most of the design was done to optimize fabrication. It has a 3D printed body formed by many parts that do not require printing support. Three wooden bars hold the strength of the mousetrap springs so that the 3D prints don’t break due to tension.
I went for the “box” design rather than the typical curved design of the Claymores since this simplifies printing and optimizing the internal space.




The electronic board is mostly designed from scratch and uses the Arduino bootloader. The PCB itself must be ordered from a fabhouse, but all the components are easy to find in eBay.
It allows for these functionalities:
- Local control with one button. Short presses to open and close, long presses to activate and deactivate.
- Remote control with a small RF remote.
- LED and buzzer indicators.
- Excellent battery life. I applied every technique I could to save energy.

And here are two videos of it firing:
hi, i’m interested in your project i would like to know if we can talk because i would like to make one of these for me
Sure. After a little bit of retouching, I could post all the project files but be aware that they’re not in a tutorial format.
You’d need to find out how to 3D print stl files, manufacture gerbers, source and solder electronic components, load an Arduino program into an ATTiny84…
If you want to modify the enclosure or the PCB you’ll also need to use Solidworks and Altium, respectively.
if you can send me all possible information from links to all the pieces and also the schedule and some very detailed images for me to understand to barbosa.1992@outlook.pt
Hey. Just so you know, I’m working on making the files presentable and will upload them here sometime this week.
Done. Check the Download button I added in the article.
Thanks a lot friend its really help
