Someone (*cough* me *cough*) accidentally pulled the center output shaft on the practice robot.

Did you consider rivnuts or other captive nuts? When combined with a cordless screwdriver and the appropriate bit, this could be just as quick to remove and replace as a rivet -- without the shavings and need to keep a big stock of fasteners in the pit.
