After numerous iterations of thoughts, plans and models, I finally started designing this mini crossbow for the #3dpgnerf4um2 competition, hosted by 3D Printing group of Facebook. I wanted to accomplish three specific things with this project: 1. Make some that is kid friendly and can be used as a toy 2. Make it as simple and fun to build as possible 3. Use little to no parts apart from the printed ones And I ended up designing this mini crossbow. A simple crossbow would be truly a boring thing to design or make so I wanted to add a bit of extra to it. So I ended up designing a mini crossbow that have manual forward/backward motion via four wheels, left/right and up/down via manual gears. This models put a check mark next to all the three things that I planned on incorporating: it is kid friendly (and can be very colorful!), it is simple, yet fun to build (you will see!) and it uses only a regular rubber band (and the NERF dart; couldn’t do anything about it).
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
