You know… so if the handle on your coffee mug is on the wrong side you can just spin it around to grab a hold of it. Ok, maybe you will not need it for that but it is still kind of fun. A mini turntable mechanism for displaying things or just as a fidget drink coaster.
I conceived of this yesterday, whipped up the design and printed it just so I could continue procrastinating about my accounting and taxes. In fact, I was working on the segmented XL Lazy Susan and diverted to this for fun (and additional procrastinating). It was a super fast design because it uses the same dimensional profile as my other Lazy Susan’s v2.0 with conical bearings. The only thing I needed to revise was the slope of the conical bearings and the top and bottom bearing surfaces.
It spins very well but I did need to stick on some little sticky rubber feet to prevent the entire mechanism from spinning on the table surface. Other than that, print and play!
The mechanism requires 16 pin bearings which are organized in a set of 8. So print it twice. While it will not matter too much, the pins are designed to be pressed into the pin carrier from the underside (print bedside) and the print bedside should be down when the housings are assembled.
The top and bottom housings press together with a snap-fit.
I recommend a very light layer of synthetic lubricant on all internal parts. It moves much more efficiently once lubricated.
