Just wondering if the current induced be manually pushing a 3d printer bed around, can damage the printers circuitry?

Unless you are pushing the bed with 10G of force , the answer is no. You will induce a couple of milivolts , maybe a volt at most.This is too small of a voltage to damage anything.

I can very easily spin the shaft of a small D.C. Motor, and generate over 3 volts. Moving a bed even rather slowly looks faster.

It would took several hundred volts for you to damage something , you have nothing to worry about.

unless you have a badly designed circuit,no.

most motor drivers have diode protections built in.
