If you need a motorized turntable for filming or simply displaying your latest project, here’s an easy 3D-printable option from Ali of Potent Printables

The design takes two forms—one using a full-sized hobby servo, and a smaller version that employs a micro servo for motion, both of which are set up for continuous rotation.

Electronics for the project are fairly straightforward, with an Arduino Uno powering the tables via an Adafruit Motor Shield. While this could be expanded for different I/O or sensor use, the clever bit of this configuration is its interchangeable design. A master circle is connected to the servo horn, while the swappable plates attach to it with magnets, accommodating a flat surface, mounting holes, or even LEGO bricks.

Many DSLR cameras can be operated with a simple infrared signal, making them perfect targets for Arduino control. Travis Antoniello took advantage of this with his brilliantly simple 3D scanning rig.

Electronics are handled by an Arduino Uno, which commands a stepper motor to rotate a scanning platform 10 degrees per photo. After rotation, it stops for a set amount of time to let scanned objects settle, and triggers the camera, a Nikon D3200, via an infrared LED. It then repeats this process over and over until a full set of photos is taken. 

Code for the build can be found on GitHub, and the device’s 3D-printed components are available on Thingiverse. The project video seen here gives a good overview of how it works, and the scanned object on display just after 2:30 looks absolutely brilliant.
