Total noob here (never touched Arduino before today), & have pretty much no hands-on technical experience (although with lack of experience, I make up in enthusiasm to learn!)

Question: How do you attach a plate (material of plate yet to be decided, likely stiff cardboard) to a stepper motor? See image demonstration below:

Do I punch a hole in the middle of my plate and super glue the hole to the motor shaft? 🤷

The end goal is to have a rotating plate like a microwave (the plate will hold some items).

Summary; How do you securely attach a plate to a stepper motor without it collapsing from the weight of the plate? Should I even be putting a plate onto a stepper motor? Or should I use a servomotor?

Thank you!

    $\begingroup$ Noting cross post from arduino.stackexchange.com/questions/85307/… The advice Majenko gave about rollers to support the weight was good. The stepper and coupling can bear very little weight. $\endgroup$

Have a Google at double flat drive couplers, sometimes called oval, or dual drive flat.

Something like this might do the trick: enter image description here
