I’ve designed and printed a small sliding support that clips on the underside of the base and floats 0.2mm above the actuator (see dark blue piece). When there is downward pressure it will contact the actuator and limit the vertical movement of the bed. If you make 4 of them (2 of each side) and install them in the front and back you will get containment in both directions.  
Here is a link to the geometry in thingiverse: [Snapmaker A250 Sliding Support by ppmendonca - Thingiverse](https://www.thingiverse.com/thing:4779318).  
It’s still a work-in-progress, but I hope it helps. Any comments are more than welcome.
