Blaster for 13.5mm foam darts (like Nerf darts)

thingiverse

This blaster is an awesome, truly functional, and very cool shooting riffle designed to fire nerf compatible foam darts. It works as a semi-automatic AR-style rifle and is mostly printed, except for the two motors that need to be used and some screws, nuts, glue, and threaded rods. The prints are massive. This means that printing will take quite some time, like days. I hope you guys will have an amazing time making this blaster together with your kids. As you do, they will fall deeply 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 than $50.00. Print Settings: Printer: Any 3D printer will do. Resolution: 0.2 Infill: 25% Notes: 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. Post-Printing: Sand the parts, bind them together using 5mm threaded rods and use glue if needed. Things you will need are: Two motors - 30mm, 12-volt DC Two 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 Eight AA size batteries. This thing is about a 150-hour print and uses a little bit more than one kilogram of filament. How I Designed This: The blaster was drawn in 123D Design.
