Constructed by HackADay user mircemk using as many 3D printed parts as possible, this self-balancing cube uses an Arduino Nano microcontroller and MPU6050 gyroscope / accelerometer to control 3 motor-driven reaction wheels to keep itself balanced — even standing on one corner on a slope! Me? I can’t stand on

This is a video of a 3D printing technology that involves using a needle to extrude silicone objects directly into a water-based gel, so there’s no need for additional support while printing. In the video, a silicone handbag is printed by design house coperni for a show at Disneyland Paris.

3DBenchy is a computer model of a small boat designed specifically for benchmark testing the accuracy and capabilities of 3D printers. And Youtuber Emily The Engineer decided to try 3D printing one large enough for a person to sit in, and, ideally, function as an actual boat. The final result

The brainchild of maker of things Ivan Miranda, this is a giant 3D printed marble clock that tells time using black and white marbles as a dot matrix display. The clock features a marble elevator, at the top of which it uses an array of infrared sensors to determine black

This is a very worthwhile video of Australian TikToker Dazza’s quest to 3D print the perfect home for a green tree frog that was living in a fence pole on his property. He starts with a basic home model that fits on top of the pole, before replacing it with

Available as a 3D printable file from JBV Creative, this sine wave machine features marbles that roll in a sine wave as the machine is cranked. Hate cranking? Get creative and add a motor. Or a car engine! JBV also sells the file for a wave machine that’s only 8

This is a video of engineer and tinkerer JBV Creative constructing ‘The Corporate Machine’, a piece of kinetic wall art for his apartment that represents the tireless churning of big business. Using 99% 3D-printed parts, the machine launches ping-pong balls and catches them, repeating the process indefinitely until a power

This is a video of South Korean Youtuber 3D Sanago using a 3D printing pen to craft an impressive Blastoise figure, then adding all the necessary components to make it a functional humidifier. That’s cool. Now make me a showerhead that looks like Magikarp! That’s always been a dream of
