This blaster is a truly working and very nice shooting riffle to fire nerf compatible foam darts. It works as a semi automatic A.R. style rifle and It is mostly printed, except for the 2 motors that have to be used and some screws, nuts, glue and threaded rods.
The prints are BIG. This means that printing will take some time, like days :-)
I hope you guys will have a great time making this blaster. Please make it together with your kids and show them how much fun it is to make a cool project like this. As you do, they will fall in love with designing and 3D printing.
Please consider buying me a cold drink, as a blaster like this would easily cost over $150,00 to $250,00 to buy while you can now make it for less then $50,00.
Make sure to print the parts one after the other. Don't do more parts together on one build plate.
Also, check the laws in your country. Printing this in all black would not be legal here in the Netherlands. Some countries may want you to have an orange barrel and shoulder part.
Sand the parts, bind them together using 5mm threaded rods and use glue if needed.
Things you will need are:
- 2 motors 30mm - 12volt DC
- 2 m5 threaded rods
- Some glue (I use hot glue)
- Nuts and rings m5
- Foam Darts, like Nerfs or compatible darts
- Battery inserts (springs and a plate) to make the power supply
- 8 AA size batteries.
This thing is about a 150 hours print and uses a little bit more then 1KG of filament !!!
The blaster is drawn in 123D Design.
