thingiverse

This compact turntable operates smoothly with a single AAA Battery, capable of approximately 5 revolutions per minute. Watch it in action: https://www.youtube.com/watch?v=vICn143UKjQ The gearbox and motor are pre-assembled by Chinese vendors, easily found at online retailers such as Gearbest (https://www.gearbest.com/multi-rotor-parts/pp_350267.html) or eBay (https://www.ebay.com/itm/LD02-Square-Geared-Motor-Model-Gearbox-Set-DIY-RC-Car-Parts/252682875117), available for a few dollars. The unit functions reliably, but minor imperfections are expected at this price point. Some motors may require manual assistance to start, typically while the battery is connected. Place any object up to approximately 200g on the turntable's plate to draw attention to it. The photos and video showcase a screw as an example object, a playful use of words in German that couldn't be resisted.
