Check it out on Monday | Three fun DIY 3D printing projects

As Christmas approaches, what's more to celebrate than to learn about the three interesting DIY 3D printing projects that have been recently shared? Some of the perfect 3D printing cookie molds, 3D printed ukulele helpers, 3D Print technology to modify the headset.

1. Nod Bang uses 3D printing to modify headphones

We all like to nod our heads from time to time, whether it's hip-hop or hip-hop songs by DJ Jazzy Jeff, Flash Grandmaster or some other percussion instrument, but what if you nodded actually made a rhythm rather than just responding? The rhetorical question has been answered by Nod Bang, the new device can modify your headphones to make it a musical instrument for playing toys.

The Nod Bang uses an accelerometer to connect to a pair of headphones, which provides motion data to the Arduino board and custom code to nod each head into metronome-type beats The output speed is dictated by the wearer , Four 3D-printed Backlight Arcade buttons on the top of a control box connect to modified cans and a laptop to add more MIDI sound to the mixes Synthesizer drones and other effects Can be used to enrich your nod to become a complete floorfiller.

Andrew Lee, an engineer, says it took him about 60 days to develop the project, apparently allowing people to take a few minutes to try it out.

Small musical instruments are not always the easiest to grasp , But for music beginners and even seasoned guitarists, EasyKu's design makes it much easier to play chords, and using 3D printing is cheaper.

Designed by a team from Kaist University in South Korea, they are not only music lovers but also skilled 3D printing enthusiasts who can also make CAD files available online for free, so anyone interested in picking up cute mini-guitars can Modify your EasyKu device to your liking. More advanced players may want to add extra buttons to play more advanced chords, or they can modify attachments to make them more aesthetically pleasing or comfortable.

3D printing enthusiast Adam now grew up in Ohio with a feeling of nostalgia for the growth of these things, so he started to create some unique biscuit molds to make his own model on American soil. Constructed by consumer FDM 3D printers, he seems to think that the plastic material they make may have something to do with what you want to eat.

Die design is a traditional pattern in Brussels and the surrounding areas such as waffles and wind turbines.They can be downloaded and sent to your own 3D printer on Thingiverse for a total 3D printing time of less than a few hours.He Even share homemade dough recipe.
