Yet Another Motorized Lazy Susan Spinning Platform by jakabo27

Last crawled date: 3 years, 4 months ago

I designed this simple spinning platform to rotate a 2 foot wide platform on a lazy susan base with an Arduino and a limit switch to home it. The stepper motor and driver I used can't spin very quickly, so maybe use a different motor or driver if you're needing speed. I have included files for Fusion 360 (f3d) and STEP files for if you use other platforms. I hope this helps someone, at least with inspiration if nothing else. All holes are 2.7mm and should be easy-ish to screw M3 bolts into for easy assembly.
Parts List
This project is designed to use the 6" Lazy Susan Turntable from Amazon using a small ish number of 3D printed parts. It is assembled by M3 bolts that use friction to screw into the plastic. If you're feeling lazy you can use a power drill with the right bit to screw in the bolts.
6" Lazy Susan
Small 28BYJ-48 Stepper Motor that comes with Arduino starter kits
Arduino Uno or other microcontroller
GT2 belt and geared tooth pulley
M3 bolts of variety of lengths, and a few small washers for attaching to lazy susan
Access to a 3D printer
Recommended changes
If you need more precise movement without slippage you might want to glue a GT2 belt to the circle ring itself. My project works on friction because a few millimeters of slippage doesn't matter for my use, but for something more precise you'll need better grip. Once again don't expect crazy fast speeds with it.
Note - it's currently a little flimsy if you don't glue it down to a base. I am done with the project and don't feel like improving it now, but yeah expect to need to attach it to a base board. I just used hot glue.
