You may be able to 3D print a simple flexible coupler.

Automotive steering shafts often use a simple rubber 'donut' with the shaft fixed to a tee piece that is bolted onto the rubber.

They are arranged 90 degrees to each other so that any misalignment is compensated for.

Hi Doug,

I'm having the same problem with gearing. I will probably end up using some sort of belt drive also.

Hi Doug,

I have dealt with gear motors and position sensor systems in dental chairs. These actuators use a worm drive off the motor shaft which turns a jack screw actuator. The motion can be very slow and position controlled. The motors are AC bidirectional and are usually controlled with triacs. Sensors are usually linear or rotary potentiometers. I do not know if this technology would be of any help to you but is you have a local dental equipment repair shop or person a trip to their parts graveyard might be of help.
